our customer feedback

Patrick in April, 2024

Got a second car undersealed by preserve & protect and the standard of work was just as excellent as before. Great communication and quick response times, been supplied with pictures of the work all the way through the process as well. The guys offered good advice and I was consulted before any decisions on the type of finish were made.
Definitely recommended!

Marcin in April, 2024

Great and fast service, keeps you updated with photos. Very friendly and informative. You can see such a huge difference before and after! I can highly recommend!

Jose in April, 2024

I discovered this gem of a garage on forums and to my surprise, on arrival with my GR 86, there were two other GR / GT 86’s recently treated. Despite being new, initial photos revealed small areas of rust already setting in which were expertly spotted and treated by this brilliant team. The entire chassis was under-sealed & I was kept updated throughout with photos and explanations each step of the way. I cannot recommend them enough to anyone looking to maintain their automobile the way it’s meant to. I’ll definitely be back soon.

Simon in April, 2024

Just had my old VW T5 treated by Preserve and Protect and must say I am very impressed with the customer care, attention to detail and professionalism. I was kept informed throughout the process with regular updates and photographs from Sam, and Mark and the team in the workshop are friendly and can’t do enough for you and a pleasure to deal with. I can’t recommend the overall experience and service enough and will 100% use again. Thanks Sam, Mark and the team, see you again for annual check!

Matthew in March, 2024

Got the underseal from these blokes and the place is second to none, great communication as the job was being done (photos sent so you can see the progress of the underseal taking shape). Was able to collect my car the following week and safe to say I will be using their services again for any future jobs needing done.

Brilliant stuff.

Clive in March, 2024

Just back from a yearly wax health check at Preserve & Protect. Again excellent service which couldn’t be faulted, I always feel so welcomed.

As my vehicle was treated from brand new and the thoroughness of the treatment there was no deterioration in the wax despite it being a daily driver, there is still no rust present on my vehicle.  There was no charge for this health check, they re-injected cavities for me also just on a preventative basis.

If you want your vehicle to look after you, you must look after it in return. Once the rust starts it can become more challenging to maintain, talking from experience here.

See you all same time next year and once again Thank you, I am loving my car.

Bryan in March, 2024

Our heavily salted/gritted roads and the Scottish Winter had already started to take their toll on m year old GR86. Although it had less than 1K miles on the clock, certain areas were already beginning to rust. The guys at ‘Preserve & Protect’ (Johnstone) did a first class job in making the car’s underside look as if it had just rolled off the factory floor. They ensured that the car kept an OEM look with the correct application of clear coats and waxes – underseal doesn’t always have to be black!

I was also kept bang up-to-date with the car’s progress through regular photo updates and messages.

Highly recommended – Five Stars *****

James in February, 2024

As a returning customer I highly recommend these guys for ensuring that your pride and joy is safeguarded against the elements.

Unfortunately for me I didn’t return for yearly inspections that intended on doing since having the underseal done on 2017, life gets in the way!

Some rust spots and sill requiring welding, preserve and protect arranged all this for me as a 1 stop service. Communication is top notch and I was kept updated at each stage with photos and cost considering extra work was required.

l’Il be back every year now to ensure my 2005 Toyota Celica GT is kept maintained and rust free!

Thanks to Mark and the team!

Alistair in February, 2024

Absolutely brilliant work. Kept informed by messages and photos from start to finish.

Can’t praise them enough for the level of workmanship and attention to detail. First class job, thanks guys.

Fergus in February, 2024

These days you get what you pay for. There are cheaper options out there, but Preserve and Protect go above and beyond to deliver a first in class service. There is a reason that they only do under vehicle protection and do it right. The team are happy to provide a free inspection and then discuss various options before booking the car in. Once dropped off (near a train station which is very useful) the car is stripped down underneath, cleaned and carefully inspected. Any corrosion already present is treated, before applying various other wax based products to keep the car fully protected for years ahead. Not only is the service first class, but they also keep customer updated with pictures of the work being done and very happy to discuss additional options at a very reasonable price.

Alasdair in February, 2024

Recently had my GT86 undersealed. Communication was very good. Friendly team when I dropped and collected car and regular updates and photos when the car was being treated. Will be back for my check up in the summer.

David in February, 2024

This is the second car I have sent to Preserve and Protect as several mechanics who worked on my first car treated by them compliment the quality of the undersealing. This time I particularly like how they have smartened up the engine bay which was beginning to show its age. The car is 17 years old.

Their service is excellent and it is fascinating to see the before and after pictures they send to keep you updated on progress. All done on time and no mess.

Peter in February, 2024

Excellent service from start to finish. Great explanation and consultation, very helpful and excellent work. Would thoroughly recommend!

Pamela in February, 2024

A big thank you to all at preserve & protect for working on my Land Rover, I am thrilled to bits! The garage that carries out my mot advised it was now time to get some protection applied before large repair bills. The garage had seen a lot of vehicles preserve & protect had treated and they were blown away with their accuracy. I would recommend anyone to use preserve & protect, they are very knowledgeable and from first contact didn’t disappoint. Thank you also for staying open later for me to collect the Land Rover, It’s a 5 stars from me * see you all soon for wax health check.


Ken in February, 2024

My 19 year old 2005 Audi TT Mk1 went in to Preserve & Protect for a de-rust and Dinitrol underseal. Mark, Ross and the team did a great job, fast and friendly and so helpful. I am delighted with the result and now have peace of mind that my TT’s underside is fully protected and will keep the car protected. I studied up on Dinitrol and it is a highly regarded Swedish product that has specialist companies applying it all over the world. have no hesitation in recommending Preserve & Protect for your vehicle.

Stewart in January, 2024

I have a 2013 m×5 while at a vintage car show I got speaking to someone who had a mark 1 mx 5. I happened to mention to him that the only thing that concerned me was underbody rot. He recommended preserve and protect. Must say I am delighted with all aspects of dealing with this company not only did they do an excellent job sending me photographs of all stages. Condition before treatment, post needle descaling, clean up then application of clear coat rust converter this being allowed to cure before primer and wax was applied including cavity wax injection and weld seal application. They also ensured all drain holes were clear. I was also pleasantly surprised to learn that I get free annual underbody inspections with any repairs to the protective coating carried out for a nominal fee.


Elvan in January, 2024

New vehicle treatment needs to be talked about more, after returning my first vehicle to dealership due to a poorly preserved underside,  I knew when I had my dream vehicle I needed to get it protected. This is the only way to prevent them from eventually falling apart.

I couldn’t have asked for a better service from Mark, Samantha and their workforce, reassured me from the word go!
If you have a new vehicle or thinking of buying one please get in touch with these guys and get your new vehicle protected, keep the value in your future investment.

Thanks for the coffee too boys, hit the spot.

John in January, 2024

If ever I needed a reason to have my VW T6.1 van undersealed it was reinforced by my 3 hour drive down to Johnstone on roads covered in a toxic mix of water and copious amounts of salt……the joys of driving on Scottish roads in winter! So if you want your pride and joy protected from the corrosive mix of salt and water then pay Mark and his team a visit.

Great communication from the outset and a meticulous attention to detail.

Fleming in January, 2024

Really pleased with the service from preserve and protect. They were really helpful and recommend what process to go for with the condition of the car. Enjoyed following the process via many detailed pictures sent at the end of each working day. Fleming – GT-R

Vish in January, 2024

2nd time I’ve used P&P this time with a 2013 RS4 (previously a 180SX). Mark, Sam and the team were great to deal with – clearly car enthusiasts and care about doing a good job and protecting new and old cars from rust. Very professional and the free yearly inspections is a great thing to offer.

Josh in December, 2023

I was utterly shocked by the amount of corrosion already present on my brand new vehicle. Thank goodness for preserve & protects services, I had no idea how quickly rust can set in. If you have a brand new vehicle please, please get it treated as soon as possible. With manufacturers cut backs this is an area they don’t pay much attention to.

I received progress Images of every stage of treatment  and to be perfectly honest staff members couldn’t have been more helpful. Each point of contact has been highly professional and honest. I would have no hesitation in recommending Preserve & Protect. I look forward to coming back for annual wax health checks. Thank you for your hospitality!

Alastair in November, 2023

Service is excellent. Customers are kept fully up to date with progress. Communication is great and the work is to the highest standard. Would thoroughly recommend.

Steven in November, 2023

Really happy with the work done on my 1995 VW Golf. The communication was excellent, from the initial inspection, then the week the car was in. Lots of photos on a daily basis to show the progress. Would thoroughly recommend!

Duncan in November, 2023

Amazing service and fabulous value for money. Really clear description of what would take place and then daily updates with the whole procedure photographed and sent over to me. Real professional crew. Mark and Sam are great people to deal with. Best money I’ve spent in a while. Restored my vintage Jimny so she is tip top. And the free yearly checkup, with retouches at cost, is the ultimate security. Thanks guys!

Gerald in November, 2023

From first contact I have been very impressed by preserve & protect. I emailed and got a reply back within five minutes answering all my questions.
All treatment options were fully explained to me after a visual Inspection and I was able to view my vehicle before and after treatment on vehicle ramp. I got images of every stage of treatment and after care instructions given.
It is very refreshing to see a company who have fire in their belly and dedicated to their work. Thank you for the excellent service, I won’t forget your kindness and the coffee was on point too. See you for annual wax checkover!

Thomas in October, 2023

I revisited Preserve & Protect for some additional work, and they once again surpassed my expectations. The team promptly and excellently completed the sill work, staying true to their word and displaying their commitment to quality service.

Not only did they address the sills with precision, but they also generously touched up small patches of the underseal, displaying their attention to detail and dedication. To my surprise, they identified rust in the battery cavity of my boot and promptly treated it, going above and beyond what was expected. Additionally, they took the initiative to paint my rusty brake calipers in a beautiful silver, adding a thoughtful touch to their already impressive service.

I can’t emphasise enough how much I appreciate their genuine care for my car, providing these additional services at no extra charge. Sam, Mark & Team embody honesty and true craftsmanship. I wholeheartedly recommend their services to anyone seeking top-notch undersealing expertise. I’ll certainly be returning for any future needs. Thank you again, team!

Ann in October, 2023

My Honda Concerto was given a full vehicle underseal and cavity wax injection in 2022. It received its annual inspection, which involved a wee touch up, and its cavities were re-treated. The Honda passed with flying colours due to the dedication and enthusiasm of Mark and his team, and the annual inspection puts my mind at rest in the fight against rust.
Thanks again for everything.

Keith in September, 2023

Mark and his team did a super job on my car! I am delighted with the results and they sent me pictures at every stage of the process so you could see the work being carried out at each stage! I thoroughly recommend this company! The underneath of my car looks like new!

Mr D Wylie in September, 2023

Great service, can highly recommend. My car was put up on the ramp and I was able to see what was needed to be done. The options, processes and prices were fully explained to me. Mark and his team couldn’t have been more helpful.


Andrew in September, 2023

Thank you for the great speedy service!

mx5 – annual Inspection

Callum in August, 2023

My vehicle had never been rust protected which is silly as I have owned it from new. Lesson learnt.

It came back from MOT and failed due to excessive corrosion. After the amount of money I have had to spent to repair I really feel I should have looked after it better from new, kept an eye on things instead of letting it get so bad. I just wasn’t aware of how bad rust can be.

I really would be lost without the team at Preserve & Protect, they took all my stress away. They sourced all the repair panels for me and paint, corrosion fully cut out and fresh metal welded in to an extremely high standard. All Images sent direct to me of every stage.

I fully appreciate now that I need to take care of my old motor if I expect it to last and one thing is for sure….. If I ever treat myself to another new vehicle I most certainly will take it straight to Preserve & Protect without a shadow of a doubt.

I will be back for regular Inspections and I fully appreciate the Importance of this. Thank you for saving my old pride and joy!



John in August, 2023

I can’t thank the hard working team at preserve & protect enough. I was horrified to see that my brand new pick ups underside was showing corrosion along all welded seams. I am grateful this company was able to address this and prevent the spread of it getting worse. If you are going to buy a new vehicle please, please check the overall condition for rust and take it to preserve & protect, don’t look anywhere else. This company is highly professional and I like their straight talking, no messing around. They just get the job done with fantastic after care.

Big thanks also to Samantha for organising everything for me, you are a True Diamond, you went the extra mile for me and I’m grateful. See you next year!

Gavin in July, 2023

I recently had my classic Lancia Delta HF Integrale fully undersealed by Preserve & Protect. Having had the Lancia newly restored I needed someone to ensure it stayed rust free! Mark and the team didn’t disappoint, the work was to an exceptional standard using a combination of primers and wax and the follow up Inspections shows their commitment to ensuring it’s a long-lasting solution. I wouldn’t look anywhere else if you’re serious about protecting your car.

Ian in July, 2023

Can’t thank you both enough for the cracking job you’ve done on my wife’s wee jimny. Thank you so much for doing such an amazing job.

Gordon in July, 2023

Just got my yaris back after a week at preserve and protect what can you say, excellent communications as the work was being carried out , daily photos sent to show what progress has been made , a very professional business and just looking at the number of other cars and other vehicles being worked on , and parked awaiting collection so they are obviously doing something right…I thoroughly recommend using them if like me your car is starting to show signs of aging…all at a very affordable price . as I said , recommended.

Alex in June, 2023

Treating a vehicle against rust when brand new was never something I considered as the vehicle is ‘new’ why would you need to? My last vehicle got eaten away with rust and it cost me many repair bills, it got to the point no garages would work on it, became a real headache. I am determined not to let my vehicles get in that mess again.
I have been coming back to Preserve & Protect for the last seven years and my vehicle would not be looking as good as it does today without them. Thank you to Preserve & Protect for educating me and early Intervention is the way forward.

Donald in June,2023

Fantastic service from start to finish and attention to detail hasn’t gone unnoticed. My pick up is looking the best it ever has thanks to Preserve & Protect. Exceptional communication, nothing was any trouble for the team, they helped me with additional work and took no extra payment for this although offered. Thank you very much and see you in a years time for wax health check.

Thomas in May, 2023

I’ve taken my 20+ year old car to these guys and they’ve done a magnificent job with it. Rust had started to creep in and I’m glad I left it with the team to deal with on time. Thank you.

John in May, 2023

Great service as always on my Ducato camper annual protection top up plus treatment of a couple of other things they noticed ????

Craig in April, 2023

A brilliant job and service by Mark, Sam and the team on our 350Z.
Had considered getting the full Dinitrol treatment done as a preventative measure for a while now, as the car spends 360+ days a year sat in the garage… After a really positive and informative discussion with Mark we finally decided to go for it and are really glad we did.

Daily updates with photos, of each stage of the process and really detailed feedback after the job was complete (which was nice to know there were no nasty surprises and everything was solid, and now fully protected!)
100% recommend P&P Johnstone… will be getting our other cars booked in after this brilliant experience.

Gregg in April, 2023

I had my MX5 in for an underseal at Preserve & Protect. I was talked through the whole process before I had dropped it off.
Sam kept me up to speed with daily photos of the work.
Mark was very helpful with tips and hints about MX5’s. I even got my gearbox and diff oil changed! Protect & Preserve are a great company and I can’t recommend them highly enough.
Thanks guys.

Clive in March, 2023

Great job on my Musso from the team. 3rd Vehicle we’ve had done by these guys. Excellent service in every way and highly recommended. Thank you Sam, Mark and team!

Sarah in March, 2023

Preserve and Protect did a wonderful job on my Jaguar. Photos from every step of the way were excellent and Mark answered all my questions, the Dinitrol process was thorough. The car looked fabulous and I have had no issues afterwards. The price is worth every penny. 6 month check is also free!

Chris in March, 2023

Biggest thanks to all from preserve & protect who worked on my car, fantastic pleasant experience from start to finish. My car is looking excellent now.
Special thanks to Samantha who happily answered all my questions and sent progress Images over. Her dedication to the company is evident so thank you!

See you guys for annual wax check over.

Graham in March, 2023

Thanks for a Top Job on my defender
Guys ????

Grant in February, 2023

Mark, Sam, and the team at Preserve and Protect. I had a good look at your work. What you’ve done is excellent work. Attention to detail and thorough job. Most grateful to you, should have done it earlier! Well done to you all. Many thanks Grant.

Kenny in February, 2023

Having researched extensively where best to take my 19yr old Japanese import Subaru to have the underseal refreshed, I was pleased to find that the company whose name came up favourably on forums time after time were less than an hour’s drive from me.
Preserve and Protects reputation is well deserved, from the initial enquiry through to picking the car up with the work completed, Sam’s communication was excellent. P&P are clearly busy for good reason and it was a long wait for the first available date to come around, but once the car was dropped off with Mark It was hugely reassuring to receive timely and detailed updates including many photographs of the work progressing and the end result was excellent with not even the smallest spot of underseal on any of the paintwork, testimony to the preparation and care taken throughout.

The yearly checkup service is an added reassurance and I look forward to taking the car to Sam and Mark for many years to come.

Jonathan in February, 2023

Great company to deal with, and they do a superb job at a very reasonable price. Why pay a fortune for your car, only to let it rust away. Thanks to Preserve and Protect, my 21 year old car is still on the road and in great condition.

Andy in January, 2023

I was going to refresh the underseal on my Mercedes but when I discovered P. & P’s website and saw what they did I decided that they would do a much better job than I could. It would also save me scrambling about under the car with under seal dripping off my head.
Mark and his team have the process down to a fine art and did an outstanding job complete with photos to prove. I have just washed the car expecting to find the odd spot of stray under seal – none was found.
So save yourself hassle and mess get Mark and gang to do the job – it’s great value.

Tom in January, 2023

Thank you for the outstanding job, my local garage have said it’s the best underbody protection they’ve seen. I am also re-assured with yearly checkovers that my vehicle will remain in excellent condition by ensuring rust is maintained.

Gordon in December, 2022

Lads are brilliant at P&P first class job and they keep you up to speed throughout the process.
They had my Evo stripped the old protection and re done my car.
It’s always refreshing to deal with a company who are not just doing this for a living but they are also Car guys and love your car as much as you do understanding what it means to you.
Get booked in ASAP.

Richard in December, 2022

Top service, kept me informed throughout the process, well worth the cost.

John in December, 2022

Many thanks for a great and friendly service. Your photo progress updates for our VW T5 Caravelle were very much appreciated. Highly recommended!

Joanne in November, 2022

Biggest thanks to owners Mark & Samantha not only have they carried out work as described to an outstanding standard, with Images all the way. We become very ill with covid and they arranged for our vehicle to be transported back to us on completion. Once the vehicle was returned we were overwhelmed to see a “get well soon” hamper inside the car, filled with essential items fresh bread and soup to name a few.

My husband and I will be forever grateful for your kindness and generosity shown to us, covid hit us real hard.
Thank you for the fantastic service, I have no hesitation in recommending your company to anyone.

Adam in November, 2022

Had my 2006 mr2 welded and undersealed here, service was second to none. Updates throughout and fantastic final product. Car is looking like new underneath and all for a very reasonable price.


Ann in November, 2022

I contacted Preserve and Protect on a recommendation.  All my questions and queries were answered by Mark and his team very quickly and “call backs”were received within minutes.  Nothing appeared to be a problem to them and they went to great lengths to put my mind at ease (and in termsI could understand!).

I was constantly updated regarding progress, backed up by a large number of photographs, which I intend to place in my car’s portfolio.  

Mark put me in touch with Alan, of AGL Transport, who transported my Classic Car from my home, and returned it to me after completion of the work.

Since the car has returned home, I am delighted with the results, and would have no hesitation in recommending Preserve and Protect to anyone who is looking for high quality undersealing at a reasonable price and with an annual service as an added bonus.

Thank you to Mark and his team.  My 1991 Honda Concerto will live for another 31 years!!


Jonathan in October, 2022

Preserve and Protect did a superb job on my Citroen Xsara. Thanks to their welding and rustproofing, my 20 year old car is still on the road, and running great. Money well spent.
(Returning Customer – Annual Check over)

Rachel in October, 2022

I’ve had two vehicles undersealed and this is the first time one has been given it’s annual service.
As usual, they’re efficient and friendly so in and out in about 90 minutes (enough time to wander up for a coffee and back). Touched up and all cavities treated again (Phnaar)?
I really can’t recommend them enough, my MX5 will not rot like so many others

When I got my freshly imported Toyota Alphard I was looking for a business that could carry out an underseal on it I wanted it done properly by a company that I knew I could trust. I would literally have travelled hundreds of miles to get the job done right but as it turns out one of the best places in the UK to get an underseal carried out is right here in Scotland.

The team were very astute and in the space of hours I had several pictures of the underside of the car. Being a fresh import it looked great underneath but the team spotted some rust breakout areas around the manufacturers welds.

They knew exactly which products to use and how to use them in regards to the condition of the vehicle and kept me updated with pictures and information throughout the process. You can see from the pictures the level of care and attention they put into their work, everything is done properly to the highest of standards.

All of this work was carried out for even less of a cost than I was expecting, it’s great to see a good Scottish business providing such a high quality service right across the board. Next level, high quality workmanship, from lovely friendly people and all at a great price! What more could you possibly want.

I cannot recommend Preserve and Protect any higher, they excel at what they do and if you have a vehicle especially a vehicle that’s clean underneath such as a fresh import do not hesitate to get this done as soon as possible. The salt on the roads here just destroys our vehicles.

Thank you so much Preserve & Protect for the work you carried out on my freshly imported Toyota Alphard. What an outstanding job you did with it and high quality service you provide, I couldn’t be happier.


Lee in October, 2022

Really professional and thorough service from Mark and the team . Constantly kept up to date with progress at all points through the process by Sam and what a finish ! I can now sleep easy that my Defender 90 is protected thoroughly through the winter months . The service is efficient and knowledgeable and the peace of mind given by the commitment to yearly inspections means I will hopefully stave of the corrosion perils of Landrover owning ? I would definitely recommend these guys to anyone looking for quality undersealing.

Paul in October, 2022

I found out about Preserve & Protect whilst searching for a rust protection company in Scotland to do some work on my 17 year old Mazda Mx5.
After getting in touch I was greeted by Sam who asked If I could bring in the car for an Initial Inspection. On a rather wet morning I met Mark and was treated to a cup of coffee and an In-depth explanation of everything that would be done, whilst under the car inspecting on one of their many ramps they have in-house.

Based on that first meeting I was more than happy to have Mark give the car a full rust protection treatment, they also arranged for refurbishment of original scruffy alloys to be carried out.

Mark and his team are Incredibly busy so the car was booked in for late September. During the cars treatment I was kept up-to date on progress with regular photo updates, the car was away for five days.

Ive collected the car and I am so happy with results, underside now looks as good as new and the alloys in their new anthracite finish, spectacular to look at.

I’ve absolutely no hesitation in recommending Preserve & Protect to anyone wanting to protect their pride and joy. I’ll look forward to seeing Mark and team again when I take the car back for its yearly check ups but if I’m in the area I’ll stop by to say Hello as they’re just great folk!

Thank you ?

Dave in October, 2022

Thank you very much for putting some serious attention to detail into preserving my GTR.

Slight rust had started to take hold underneath and the guys spent five days prepping, cleaning and protecting the car.
Photos were sent of each stage and the car will last forever now.

There we’re a couple of extra things I asked for and the team done that no problem. Thank you again, very much.



Douglas In September, 2022

When reading testimonials people sometimes just think its made up by the company. In this case you would be incorrect in assuming that. Over the past four years I have had four cars treated by Preserve and Protect, the last one being my Daimler Double Six. I have also recommended them to five friends who in turn had their cars treated by them. Mark and his team carry out a very high quality service and really take car of your car, while in their care. They keep you informed on a daily basis and send photos of the various stages of the treatment. I cannot praise their service highly enough.

With thanks Douglas Taylor

Alan in September, 2022

I put my discovery 3 into preserve and protect last week after their services was recommended by a mate who had his defender undersealed.
Throughout the whole process Mark kept me up to date with the stages of work. In addition they took on further work with refurbishment of Alloys and fitting of chequer plates to the bonnet. I would highly recommend Mark and his team to anyone looking to have their vehicles chassis protected. Many thanks guys.

Steve Lawrence in August, 2022

Had my Mazda done last year and I know he gets plenty of them to do. Brilliant job. Just had my yearly check up and again Brilliant job. I wouldn’t hesitate to recommend and one of the nicest guys you can meet.


Mr Rodger in August, 2022

Thank you for doing my car which I
am impressed with. Very happy with
paintwork and all the rest.

Thanks again.

corrado vr6 In July, 2022

This is the first time I have used Preserve and Protect. I wanted to protect the underside of my car and was considering doing it myself. When doing lots of research and pricing the various products required I kept on seeing the name Preserve and Protect. I decided to give them a quick call to discuss the process. After speaking to them in a few occasions I decided it would be better to leave this job to the professionals, they have the right tolls and equipment to ensure the job is done correctly.

After dropping my car off I was kept upto date with pictures of the process. When I collected the car the staff took the time to talk to be about everything that has been done.

It was reassuring to know that my car has had the best possible treatment and has been done by enthusiasts who take the time to do the job correctly and care about the finished product and aftercare.

Would highly recommend and I will certainly be using again in the future

Sean Birss in August, 2022

Would highly recommend Preserve & protect. They answered all my questions and there was no hidden costs. Also a nice detail was the constant progress reports I received through the process. Not to mention they actually got my whole transit custom done alot sooner than estimated. I’m a mechanic so I was able to inspect the work myself at the garage I work at. Not that I doubted them but out of pure curiosity of what was covered. you can see alot of attention to detail. All undercarriage and suspension components covered without any over-spray.

Samantha in July, 2022

I recently took my MX5 MK3 to be undersealed and cavity wax injected by Preserve & Protect in order to ensure many more miles of smiles and not to lose it to the dreaded rust monster.

Their services came recommended; not just by those on the internet forums but by my personal friends and work colleagues

Mark, Sam and the team are great – I really can not praise them enough!

Brilliant communication starting from when I 1st made contact; the tuition on how to clean & maintain the dreaded MX5 rain drains and of course the photographic documentation of the treatment to my car.

Added to all of that; they used their contacts to ensure my alloy wheels where brought back to all their former glory.

Thanks again to all of the team at Preserve & Protect from me, my MK3 and my colleague’s MK1.

Martin in June, 2022

Amazing service once again from the guys at Preserve & Protect. Second time we have used them and have booked in our other car. The guys are very approachable and friendly, proper Petrol heads that are only too happy to show you around and explain the process. Regular updates and pictures along the way to keep you Informed. I would highly recommend and will continue to send any future cars their way.

Patrick in June, 2022

Starlet recently got undersealed by preserve & protect, worth the money and job done properly.

I couldn’t let a frame that’s so clean rust, another 20+ years on the road for this one now.

Ian in June, 2022

Excellent service and very helpful. Excellent attitude  to customers.

Alexei in June, 2022

Had my z4 in with the guys for undersealing, after a bad experience in the past (rust) I thought it would be well worth getting a rust treatment done.

Kept me updated with the process throughout and did a really thorough job. Well worth the trip from the highlands, price was very fair for the work done.

Absolutely recommended, well worth doing for the peace of mind. Thank you guys!

James in May, 2022

I’d like to thank Preserve & Protect for giving the Mazda several more years of life. Very good communication, service and workmanship. Very happy with the outcome, thanks again.

Highly recommend to combat age related rust on any car.

Kevin in May, 2022

Preserve & Protect is a company that I would highly recommend. They do exactly what it says on the tin “Preserve & Protect”. The job is done professionally and you are Involved in all steps of the process through the pictures you see. Hard working too.
I had my car back within 4 working days.



Andy R in April, 2022

To say that Jimny’s have somewhat of a reputation for rust is probably an understatement. Nevertheless, Mark and the team have done a fantastic job; Starting with a full underbody inspection with photos showing exactly what needed to be done, everything was then stripped down, prepared, one small hole fabricated and welded, followed by a full underbody underseal, cavity wax injection and weldseal application.

Whilst it was in, I had a small annoying dent in the passenger door removed using their Paintless Dent Removal service and the aluminium wheels refurbished. Everything was completed on time and on budget. Communications were excellent throughout and I am one very happy customer !!

Sorted my LWB Transit at the start of my camper conversion process. Also treated the engine bay upon request. Very happy with the job. Good communication and updates would recommend.

Thomas Campbell in March, 2022

Thanks again Mark and the team, brilliant service and a great job.

David McGorry in March, 2022

Had my subaru undersealed by Mark and his team and what a professional job they have done. They explained the process so I knew what was getting done and any questions I had. They also send progressing pictures throughout the week to keep everything updated. Very professional and friendly workforce, I would highly recommend to anyone looking for their car to be protected.

Stewart Penny in March, 2022

I first put my defender into Mark a few years ago to get properly undersealed. His professional approach gave me total faith that the job to be done properly. He sent pictures of the whole process along the way and has now Inspected my vehicle twice since first doing the job.

It’s important to look after a land rover chassis as they are known for rust. I would highly recommend getting Mark to do the job.

An extremely honest, professional and high quality job carried out by Mark and his team.

Graeme in March, 2022

Just had my Freelander in for its yearly Inspection, as per Mark’s advice on the importance of getting this carried out after the original work was done. Once again, 5 star service from Mark and the team which will help maintain the life of the vehicle. Will ensure next year’s Inspection is carried out timeously. Graeme.

Craig Aitken in March, 2022

Excellent service, took my vehicle in for the annual Inspection of the treatment that was from the previous owner and to make a booking for a top up.

Martin & Fiona in February, 2022

Mark, huge thanks to you and Stuart for doing such a fantastic job on the van it looks brand new! We’re so delighted its been given a new lease of life! So glad that we found you! Very best wishes Martin and Fiona Gillespie

Simon in February, 2022

Thanks for a very professional service. A very informative system of photos and updates throughout. Mark has oodles of knowledge, so he’s well worth chatting to about underseal and all things car wise. Definitely commendable! Cheers, Simon

John in February, 2022

Exceptional service from start to finish. Had vehicle undersealed and cannot praise quality of not alone work carried out but level of communication and general professionalism exhibited throughout. I would highly recommend to anyone looking for this level of customer service, sadly becoming a thing of the past in many sectors.

Allan in January, 2022

My camper van is starting to get on years! The folks at Custom Camper Coatings (Preserve and Protect) did a superb job removing rust, welding in new metal where needed, and applying new underseal protection. Progress photos were sent each day and communications were excellent. On arrival to pick up my van, there was a cup of tea waiting! I can’t recommend them highly enough.

Daryl In January, 2022

“I just had my car undersealed at Preserve & Protect (Toyota Chaser). They have not only done a super job at a great price but also explained the process start to finish with regular updates and photos.
I can’t thank them enough and I highly recommend them”.
Professionalism, Punctuality, Quality and Value

Nuno in January, 2022

I would like to say Thank you to everyone at Preserve & Protect for sorting out my 05 plate L200.

They kept me upto date with all work done and even sent photographs of each stage.

The staff were brilliant and friendly and even advised in regards to aftercare and what to keep an eye on regarding the chassis.

Tomasz in December, 2021

Great work on my A5. If you want to have the underseal done professionally look no further. Great work and updates regularly.


Alan Grant in December, 2021

Mark and his team did a great job on my Volvo V60, this is my second car that has been done by the guys. Dylan kept me Informed by sending photos of all the different stages of the process. I would highly recommend Preseve & Protect to anyone who wants their vehicle undersealed.

Ray Wilson in December, 2021

My wife & I recently bought a Motorhome from a long standing “Reputable” Dealer only to find out when it was delivered to “Preserve & Protect” to be undersealed, that it was suffering from extensive corrosion.

The efforts that Dylan, Mark, and Stewart made to ensure the best course of action for repair and then undersealing was quite simply “above and beyond”. Their honesty, advice, support and friendly “can do” attitude is second to none: as is the quality of their workmanship; and nothing is too much trouble.

Seriously folks, I will have no hesitation in making sure that they will be involved in any future work our Motorhome may require, and I cannot recommend them strongly enough to anyone considering having this work done. These guys seriously know what they’re doing.
Ray Wilson

Daniel in December, 2021

A company second to none, Car nut Mark and his team will look after your car as if it was their own, I have just had my 2019 Ford Mustang undersealed and all the cavities done by Preserve and Protect, I had my 1997 BMW E39 done 2 and a half years ago and will get these guys to do their stuff to any car I will ever own.


David Wallace in December, 2021

“Mark and his team are thorough, provide great feedback and support you through the process. I was lucky to get a booking due to a cancellation which meant I managed to protect my camper van before the gritters got to work salting the roads.”

David Wallace – Hymer Motorhome

Paul in December, 2021

Just a quick message to say thanks for the prompt service and first rate job on my MX-5. I can sleep easier after going out on gritted roads knowing that it has better protection.
As probably my last combustion engined car, I want it to last.
I’ll be sure to recommend your company to anyone considering getting their car protected.

Andy Plumb in November, 2021

At last a company that does what it says, Thank you.

Dylan kept me upto date with messages and pictures.

Don’t think twice if you need your pride and joy done.

Dont go elsewhere,  A1 Thanks


Mark Gordan in November, 2021

Great customer service having taken my wife’s mx5 in for underseal protection – progress upgrades with photos along the way. High standard of workmanship.

Brian Tracey in October, 2021

These guys are the best in the business. Got my jeep wrangler done recently and I couldn’t be happier. First class work and a friendly helpful team. Keep you updated on the whole process.

I travelled from N.Ireland to use their services and I have to say its the best money I’ve ever spent on the jeep.

Stuart Fyfe in October, 2021

I had my Tiguan mk2 done and can totally recommend this company and my garage that does my servicing says it is a great job underneath.

Pamela Horn in October, 2021

Highly recommend Preserve & Protect. Thoroughly excellent service, absolutely brilliant ?

Alexander in September, 2021

Mark and his team did a first class job on my 2007 mazda mx5. I was kept upto date with photos through the time my car was getting treatment. I would highly recommend anyone looking to have their car protected from rust to use Preserve & Protect, they won’t let you down.

Ciaran in August, 2021

Mark and the team were very professional through out the whole process. Took my 09 X trail in for a full underseal and not before time. Was pretty rough underneath but the guys at preserve and protect really made her shine again. Thanks again

Arabella in August, 2021

The service provided by Mark and his team is outstanding. The underside of our 1955 Prefect had to be stripped of rust and treated. Mark sent photographs of each stage of the treatment. When we called to collect the car, it wouldn’t start. (This was nothing to do with Mark or the team.) While we waited for the RAC, Mark provided us with tea and coffee and regularly checked to see how things were going. Lovely people and amazing service!

Elizabeth Angus in July, 2021

My experience with Preserve & Protect was very smooth and easy. Mark is very informative and helpful, and leaves you feeling reassured that your vehicle is in safe hands. I was kept fully informed of the process with photo updates, and my van was ready a day earlier than I expected. I’m delighted with the service I received, and confident that we might stave off the ravages of a Scottish winter. Thank you, Mark and team!
Elizabeth Angus

Ron Pickles in July, 2021

Just a note to say thanks to you and your team for the work carried out last month on my motorhome.  It was sold within 4 hours of me picking it up!  Having the work done speeded up the sale and value by at least £3000.
At the time, as I had locked up the spare wheel carrier, you were unable to treat it. Kindly you offered to do it f.o.c for the new owner and I’ve asked her to contact you.(she may already have done so).
Thanks again, obviously I’ll be back when I next need underbody work done.
Ronnie Pickles

Ross In July, 2021

I found Preserve and Protect to have a fantastic service. They were very helpful and informative throughout the entire process, explaining the works in detail. When the car was in for the work, I had over 60 photos sent to me at different stages, which I feel proves the honesty of the work done.
I am very satisfied with the work done and have already been recommending to friends and family!

Michael Anderton in July, 2021

Derust, corrosion protection and under sealing. Work carried out as promised, promptly and efficiently. First Impression service gives is costly but seeing comprehensive set of photos as work progresses shows clearly the care and thoroughness applied to the protection process.
Operations are well organised and Mark listens to and communicates well with customers.

Bob in June, 2021

Best under seal treatment our 90 has ever had. Very pleased with product and service and in time frame stated. Very relevant as I’m 200 miles away. Please convey my thanks and appreciation to your team. Cheers Bob

Matt in June, 2021

“I just wanted to say thank you for all your work this week and keeping me posted throughout. I am delighted with the results, Great Job!!

Paul in April, 2021

Subaru forester Yearly Inspection & touch up. So chuffed it still looks this good underneath even after a good few years. Big thanks to Mark, Sam and the team for your hospitality and ultra efficient workmanship.

Gerry Gorman in March, 2021

Update on my review.
Took my car back to Mark, Samantha and the team for its annual check on 11/02/21. Again the service was faultless from Protect and Preserve. I have never known a business and its people who care so much about their customers. Each vehicle is treated and looked after as if it was their own.
I encourage anyone who wants their vehicle undersealed to visit Protect and Preserve, you will not be disappointed.
Thank you Mark and the team for an outstanding service.
See you all soon

Stuart Conway in February, 2021

Awesome jobs guys. Thanks again. Really impressed with both the service and the finish. I will be back with a few other cars!!!

Ron Wilson in February, 2021

I wanted my Merc Vito Campervan Japanese import to be undersealed, and I wanted a quality job done locally at a reasonable price. Having trawled the web, and reviewed the options I chose Preserve and Protect: by far the best quote, the only place I could see using Dinitrol and I was impressed by the follow up checks as stated on the web site.
Having had the job done, I am more than impressed. Not only was the job done to schedule, Mark sent me photos all the way through the process so I could see progress. He also sorted a broken suspension coil that I didn’t know I had. Having met Mark in person his emphasises ‘doing the job right’ and he values and wants to look after his customers, a rare thing these days. I couldn’t be happier with the work and the service I received, and I’d recommend Preserve and Protect to anyone wanting similar.
Ron Wilson

Adam Hutton in January, 2021

I contacted Preserve and Protect after some intense research on finding the best Dinitrol specialist for my worked hard – daily driven 4 wheel drive Ford F150. Being over 10 years old, the vehicle was in very good condition with minimal rust so now was the time to apply the Dinitrol product range and keep it that way.
Preserve and Protect have review after review of fantastic feedback, common themes being great knowledge of the Dinitrol products and also expertly done application of said products. The company has a YouTube channel which I suggest you check out, the main video was professionally made and narrated, this took time to produce and get right, once again showing the passion and love for the business.
I can confirm that after P & P carrying out the full needle descale, steam clean and full underseal that I made the correct decision without a doubt.
My vehicle was dropped off Sat 9th Jan, I received pictures of before, during, and after the process providing proof that the process was definitely value for money and was being carried out correctly. These pictures will be saved for future reference. There was also some back and forth with regards to minor details of how I wanted the products applied – this was essential to ensuring that the work was done the way I wanted it to be and not as someone else decided.
Collected the vehicle Sat 16th Jan as agreed at the drop off, no delays. Results fantastic as per pictures, Mark handed me an invoice and Dinitrol certificate of work done. These will go straight into the vehicle file for future reference, the invoice also entitles you to free annual inspections, Mark asked I go back in September for a check-up – great piece of mind.
Mark has several immaculate vehicles of his own which he took some time to show me, this confirms that this company is built on the knowledge and passion of enthusiasts and not someone just out to make a quick buck with no real interest in what they are doing – this is all too common these days unfortunately – so choose wisely.
Living in Scotland, an underseal is the best money you will spend on your vehicle, if someone has offered you a cheaper price, don’t settle for 2nd best – choose Preserve & Protect.
Thanks again to the entire P & P team.
Adam Hutton

Andy in January, 2021

I found the process very professional from start to finish, I also appreciated the photos that were sent from each stage of the work that was done. Also I was very happy with the communication between Mark and Samantha regarding any queries that I had about my vehicle and of course delighted with the workmanship. I would not hesitate to recommend Preserve and Protect to anybody that would like this kind of work done to there vehicle, thanks again and will see yous soon keep up the good work!”

Mark Saunders in January, 2021

A short note to express my thanks to all at Preserve and Protect (Johnstone). I wanted to guard my Chrysler Crossfire (a future classic perhaps) from the relentless rust enhancing weather we have during our Scottish winters.

I looked around the internet for companies who specialised in automotive under-sealing. I quickly found and paid Preserve and Protect a visit. From the outset, Mark was a pleasure to speak with – it was as if we were talking about caring for his own vehicle. Having thought about what Mark had said about what Preserve and Protect do, I called to have the Crossfire booked in.

Jumping forward a few weeks, I am absolutely delighted with the final result. Someone recently remarked that the vehicle looks as though it has a brand new chassis. While the car was in their care, Mark and the team were kind enough to carry out a couple of small ‘beyond-the-call-of-duty’ jobs which not only saved me the time and effort but finished the job off to absolute perfection.

I look forward to returning to Johnstone towards the end of the summer to have the car inspected as per Mark’s hand-over instructions. What a fantastic service. Choose Preserve and Protect (Johnstone) and you will not be disappointed!

Stewart in January, 2021

I had my Land Rover Defender in for treatment recently and I’m extremely satisfied with the final result.
Mark took time to explain the exact process and the reasons for doing specific treatments on different parts of the cars chassis, including places I wouldn’t even of known needed it.
He sent pictures of the complete process along the way, this was really good for piece of mind and interesting to see the action in pictures.
I would really recommend the treatment that mark and his team delivered.

Gavin in November, 2020

Absolutely over the moon with the service of my Mx5 NC, went in for and underseal treatment and a few small rust repair sections. Mark was brilliant in informing me of the locations of these repairs and gave detailed photos all along the process, I was taken back by the professionalism of the work carried out and when dropping my car off was actually asked when I would like it back as opposed to just being told the usual “you’ll hear from us” like most garages so that was refreshing to hear! after collection I was given all the necessary paperwork including a 6 month check up date. Fantastic service Will 100% be back!

Philip in November, 2020

Excellent service and aftercare. Highly recommended ?

Stevi Jackson in November, 2020

Thanks guys. Super fast and efficient job.
Well pleased and highly recommended!!

Rob Milsom in November, 2020

Fantastic service from Preserve and Protect.
Very knowledgeable and passionate about what they do and give great advice. The updates of how the work is progressing with photos is a great idea and helps build the vehicles portfolio. Anyone who is interested properly protecting their vehicle should talk to Mark at Preserve and Protect.

Darren in October, 2020


To anyone thinking of using Preserve & Protect I can say with absolute confidence and reassurance you will not find a better and more conscientious company to put your trust in. Mark will guide you from inquiry to completion and supply photos at each stage. I have put several vehicles to Mark now and will continue to do so, I cannot recommend Preserve and Protect enough .

Stuart Berrie in October, 2020

Mark has an incredible understanding of the products, preparation and application. I received lots of pictures of various stages of the process, and completed exactly within the time frame quoted. Received documentation as proof, and asked to return in a year for free inspection of coatings applied. Fantastic and professional service, thanks!

Seamus Mac in September, 2020

A fantastic and thorough job was done on my car. Mark was informal, yet very professional, obviously a keen enthusiast. Really seemed like the right man for the job. Regular photographic updates are a really nice touch. Communication was excellent, any questions I had were answered quickly and in good detail. Annual free inspection is very much appreciated. These people really do a fantastic job. Can’t recommend them enough. An obvious 5 star rating – I can’t fault the service that I received and I am very happy to leave my beloved ST3 in their capable hands. Looking forward to seeing Mark again next year! Thanks for everything guys! 🙂

Jason White in September, 2020

As other reviewers have said, Mark and the team are very professional, happy to answer any daft questions I had, provided photos all the way through, and arranged for three sections of welding (at additional cost, though very good value, and advised this before going ahead). They were also happy to add on black strips along the sills to cover up some bodgy rust repairs/primer patches as a last minute request the day I dropped the car off.

They also helped me out again today following an incident with a trolley jack and the soft sills of my RX-8 (my own fault for jacking where these cars are weak!) – the jack had punched a hole right through, Mark had me bring it in and fixed + re-coated the hole same day, which I was not expecting, and it was done at a very reasonable cost (much lower than I had feared).

I really couldn’t be happier with the service provided. Mark has also recommended a local body shop for seeing to the rust outside of their jurisdiction (ie anywhere that’s not the underbody), and I will be taking him up on that recommendation.

Allan Craig in October, 2020

Undersealing and cavity waxing MX5 RF great company to deal with, all process was explained and backed up with photos, Mark is a top boy who knows his trade inside out, you want your car protected look no further than P&P you will not be disappointed

Paul Jordon in September, 2020

Very professional, friendly staff, with personal attention from Mark, on my 40 year old MG. Peace of mind expertise, quality products, and properly applied. Identification of a bit of rust and fixed with no problems. Lots of photographs throughout the work. Lots of advice for care afterwards, and free inspections of the work should I need it. Will definitely use again and recommend to my friends. Really easy to find, and the train nearby to get home. Thank you!

Brilliant Service. I have used Preserve & Protect twice now and on both occasions the work has been exceptional.

Mark and the team do a fantastic job and are extremely knowledgeable about what they do.

Communication is outstanding with photographs and updates every step of the way. You simply don’t get this level of service elsewhere and I’ll definitely be back with my next project.

Highly recommend!!


Ryan in June, 2020

Land Cruiser

Discovering that the bodywork of my 1994 Land Cruiser was held together by a combination of expanding foam, sealant and blind faith was a shock for me but Mark and his team already had a plan. They stripped everything back, figured out exactly how much work there would be and brought in the welder. With photos of every step along the way from rot box to welding — and some of the nicest welds I’ve ever seen underneath a car — to painting and sealing, they also took care of transportation and liaising with the bodywork shop for the exterior work, and the Toyota is now sitting pretty in my drive again, ready for the next 25 years.

Kenneth Ross in March, 2020

‘I had read good reports about Preserve & Protect Undersealing and Rustproofing Services, so decided to take my 1953 Jowett Javelin to them for rust treatment and minor underside welding repairs.
Although underseal had been applied to the chassis many years ago, this had hardened and flaked over time and was badly in need of further attention, which included removing loose and damaged areas and treating the rust that this exposed.
I have tackled this job myself, on a 1970’s MGB, but I didn’t relish the idea of trying to do the same on the Jowett, working with the car on axle-stands and only inches from my face!
Once at Preserve & Protect, and with the Jowett on one of their vehicle lifts, I was able to take a good look at the underside with Mark and see just what needed to be done.
The whole job was carried out in a very professional and thorough manner, and with the chassis cleaned, rustproofed and undersealed, I now feel that I can take the car out in all weather conditions without worrying about future rust problems!’

Mike in March, 2020

I have a 2010 Saab 9-3X project car which needed undersealing and detailing. On recommendation I used Preserve and Protect in Johnstone  Scotland to carry out the work and organise and oversee Detailing by Elite in Paisley.

The undersealing was using Dinitrol and included under bonnet protection.

From first contact the staff at P and P projected a very professional and friendly approach which continued through to completion of the work. They sent, by e-mail attachment, before and after photographs which kept me informed about progress.

The results of the work can only be described as excellent quality and the car looks like new. The cost was very reasonable considering the excellent quality of finish.

I recommend this company to anyone considering this process. A special mention of Samantha and Mark  what lovely and professional people to deal with.

Mike Chapman.

(Happy for you to publish this and speak to anyone wanting a personal recommendation).

Malcolm in February, 2020

The big Arctic was in some desperate need of attention on the underside. Step up to the mark  at preserve & Protect Undersealing , they seen to all the rust and treated the chassis, suspension components and everything else to a proper coat and cavity Injection.

I am so satisfied with the work it gives me a great feeling to know I’ve potentially avoided thousands in the future in rust repairs. 10/10.

Hugh McKergow in February, 2020

Great and superbly professional service provided by Mark and his team. If you want to protect the underside of your treasured car this is the company to use. Great service and great value.

Richard Allen in February, 2020

“The Enthusiasts’ Enthusiast. Mark and the team understand owning cars for passion and cut no corners.

Will be back soon for my checkup.”

Ross Cruickshank in January, 2020

Just picked up my Subaru after leaving it with Sam, Mark and the crew for three and a half days. I was extremely impressed with work they’d done and how seriously they take their work.
Through out the whole process they kept me up to date with photos and messages which I really appreciated as it showed me how thorough a job they were doing.
The customer service was excellent at all times as well and I felt like I was speaking with proper petrol heads which really reassured me that my car was in safe hands.

I found Preserve & Protect through Google as I wanted my 2007 Range Rover Vogue, just bought in the south Undersealed before starting a new life in Salty Scotland.

I found Mark and his team a pleasure to work with.
Nothing was too much trouble. The way to a clients heart is service, service, service! Mark kept me up to-date with every stage in the process. How much it cost. How long the treatment would take, and backed this up with a daily What’s App comments and photos.

Mark is an Underseal Enthusiast who knows his product and invites you back in a years time to Inspect his workmanship. This gives you confidence in the man and the product.

Do not let your baby rust! Phone Mark now!

I located Preserve & Protect via a search engine, read the reviews and contacted Mark and the team and I am so glad I did.
I have a classic 4Ltr supercharged V8 XKR which is my pride and joy and given I live and drive it in Scotland and elsewhere,
thought I’d better get it undersealed. Mark and the team had the Jag in over a weekend and I received lots of images of
the process from start to finish and I also opted to have the engine bay treatment carried out which was a bonus, it looks
From the initial contact to picking up the car it has been a pleasure dealing with Mark and his team, they are a friendly and
very professional bunch and you can see by how the office and work area’s are laid out, its very much old school and fit for
purpose. My Jag is now treated against rust and grit and its guaranteed. I would highly recommend Preserve & Protect for
your car. I will be back next year for the annual check up.

Jim in September, 2019

Finding a firm nearby specialising in vehicle undersealing and applying a reputable product like ‘Dinitrol’, was proving difficult prior to contacting Mark and his team at ‘Preserve and Protect’ in Renfrewshire. Work was carried out as proposed, and agreed, with photographic record of steps in the process being provided direct to the client. A few days later our
vehicles had protected undersides. Added service with a smile to the whole experience made the trip to Johnstone very worthwhile.

Kind regards, J&P Boyd

Stephen in September, 2019

Just had my s2000 in at preserve & protect, undersealing the car. Had it in here 3 years ago when I took the car up to Scotland so this was just a top up. Plus I wanted behind the bumper done, now looking great. Definitely a lot of work went into it for the price, would highly recommend.

I bought a 1997 BMW E39 from a garage in Bradford who deals in Japanese imports, The body work and underside were in very good condition and I wanted to keep it that way, I went onto the Internet and found a few companies in Glasgow or surrounding area who did this type of work, I chose Preserve and Protect after reading some wonderful reviews about them, I phoned them and spoke to Mark who explained to me in great detail exactly what the job consisted of, After talking to Mark I was totally reassured that I had made the right choice, I booked the car in, 3 weeks later I delivered the car to them on Monday, I spoke with Mark and the team who were all very pleasant and Knowledgeable, I was told I would get my car back on Friday, I received by email photos of each stage of the procedure after it had been done, The final photos can only be described as lovely, I had picked the bronze coloured Dinitrol that matched the colour of my car, I am over the moon by the job Mark and the lads done, I will be booking my 2015 Mercedes CLA 45 AMG in for the same treatment in the very near future, The car manufacturers are a bit of a joke when it comes to Undersealing their cars bound for this Country as it is totally inadequate, Well done to Mark and the team, The job is very much appreciated.

Andy in July, 2019

Excellent service and the photos of the work progress were a nice touch. My 1971 mini will live a lot longer thanks to your great work.

Chris in June, 2019

This is the second year that I’ve used  Mark and his team at Preserve and Protect . Initially it was to undertake repairs and protect the underside of the 14 year old vehicle starting a restoration project of the wagon with the annual inspection this year just completed.
Delighted that there has been no corrosion as a result , in my opinion, of the attention to detail in applying the underseal last year.
I would highly recommend Mark and his company for a first class job and excellent customer service and care. Needless to say it sailed through its MOT.

Robert in June, 2019

Mark explained the whole Dinitrol process to me and the available options. The quote seemed good value for something which would protect my 20 year old TVR chassis from rust, so we chose a date for the work. I was very impressed with the thoroughness and quality of the work. Mark and his team show confidence in their work and the product through their offer of annual inspections. I really felt that the car was in good hands, and Mark is very enthusiastic and knowledgeable about performance cars.
A1 service.

Ivan in May, 2019

Mark and the team at Preserve and Protect are simply the best. I had an amazing customer experience where literally nothing was a problem.
I recently put a mk3.75 (2014) Mazda Mx5 coupe into the workshop for rustproofing. On my arrival the car was put up on a ramp so I could personally examine the underside, whilst doing so Mark showed me all the drain holes and explained every detail of the work he and the team would be carrying out. I was also sent pictures during the course of the work which showed the before and after results.
When I went to view the car after it was completed my car was placed on the ramp again so I could be shown all the work undertaken, very impressed!
Had my engine steam cleaned and treated, door sills and rear bonnet. All amazing!
What seriously Impressed me is the enthusiasm and diligence shown which the entire workshop seem to apply.
This is most definitely the “go to” place for me and I have zero hesitation in recommending Mark and his team. There were some serious cars in the workshop and I don’t think I’m the only one who is entrusting there precious metals to these guys.
Money well spent, even better that when spent you get world class service.
With many thanks

Ian in April 2019

From the first contacts with Mark it was obvious that Preserve & Protect Vehicle Undersealing & Rustproofing Specialists was something special. The workshop and facilities were spotless an absolute credit to the professionalism of Mark and his team.
The whole works were fully explained, when I left the vehicle Mark explained he would keep in touch and provide feedback with photo back up at all stages. True to his word I was kept abreast of the whole works. I am delighted with the finish and the service provided and will not hesitate to recommend this service to anyone wanting a good professional Undersealing & Rustproofing service.
Many thanks Mark

Alex in April 2019

Earlier this month I drove my Mazda MX5 two hundred miles to Mark’s garage, for its rust proofing treatment, having read the excellent reports of his work. I’d previously had welding work carried out and wanted to protect everything as well as I could. The car was booked in on a Monday and Mark advised me that he hoped to finish it before the end of the week and would send me photos and update reports. Mark was as good as his word as I received 31 photos that same day, showing the rusty underside after the removal of arch liners etc. and prior to treatment. I received further photos of the progress after descaling, rust conversion and the application of the Dinitrol. During the week I asked Mark if he could also de-fog the headlights, paint the faded windscreen wiper arms and do an engine bay treatment. Everything was completed in time and my car was ready to be picked up on the Friday.

I was very impressed with the standard of work carried out and would recommend Preserve and Protect to anyone considering this type of rust proofing.

Mark, Sam ,thank you so much for the superb job you did undersealing my old Mitsubishi GTO. Perfect from start to finish.
Photos and communication first class as was the welcome we received when dropping the car off albeit in the pouring rain ! The lift to the station was much appreciated! Picking it up One week later in blizzard conditions !!
Although the weather was atrocious the long journey was well worth it as your workmanship is second to none.
Thanks again .

A great job was done on my Civic Type R. Very professional with great knowledge about everything they do. I received pictures of the whole process and I Definitely will use them again in the future! Many thanks guys!


Douglas in March 2019

I cannot praise this company enough, the high level of attention to the process, there excellent workmanship when carrying out the work and finally the brilliant customer service. From start to finish they kept you informed with direct contact and with photos being sent at each stage of the process. This level of service is uncommon in this day and age, well worth recommending to others.

Mark and his team at preserve & protect provide an excellent service from the first quote to the final handover, every stage is explained before you agree. The care of your vehicle is exemplary and with the free annual follow up check, you have no worries over the future of your pride and joy. Cheers and many thanks.

Ally in February 2019

Very happy with the work done by the folks at Preserve & Protect. Work done: full vehicle underseal including treatment of internal lower seams of doors using Dinitrol, plus engine bay treatment. All underbody shields and arch lines removed prior to treatment and refitted.

I knew my recently purchased 14 yr old Monaro had a reputation for minimal factory underseal and, as I plan to use it all year round, underbody protection was top of my (long) list of things to do. Heard great things via car forums so popped along for a chat. From initial inspection, talking through the process, sending me 60+ photos during the work, and just chatting about cars in general, they were great to deal with. Professional, friendly and knowledgeable – can’t ask for more and I was happy leaving my car in their hands. The only problem now is my car looks so good underneath that it puts my paintwork to shame!!! Very happy knowing I’ve done what I can to protect my car.

Thanks again Mark and team, see you for yearly check-ups and maybe for a second vehicle treatment… Ally

Ross in February 2019

I am very happy with the underseal done on my Subaru Forester, can’t recommend Mark and his team enough!
Genuinely the best service and communication I’ve had from a Garage. Kept me updated throughout the process with photos and details of each stage. The quality of the work is excellent, the difference is night and day. Very welcoming and easy to deal with. Thanks Ross.

“What a job, what a team!

I am absolutely delighted to know my car is now fully protected against our Scottish climate and road salt.
Our wee duster was purchased a year ago and although only 6 years old had lived previously on the coast and had acquired substantial rust. It had only done 26000 miles and had lain dormant most of its life but when mark showed me the underside of it I was fully convinced it was time to sell or have the work done. I decided on the later as Mark discussed the process in detail with me and it made perfect sense to have this work done as it is so thorough! photos were taken of every stage and E mailed to us daily.

A couple of days later the car is fully sealed and the rust beneath treated, I am delighted, I now have the confidence to hold onto our wee car as long as possible.

I would strongly recommend this treatment as a “must do” to anyone who values their car / vehicle.

Mark’s commitment and obvious enthusiasm to motoring and passion for the same shines through.

This was a pleasure, thank you so very much, Mark and all your talented team! The car was collected in the best condition I have seen it!!!!!

We will be back!”

Thank you very much!

Christopher in January, 2019

Great job guys,
I am so happy to know my car is protected against the Scottish elements.
My focus is only a year old and I had only done 2200 miles but when mark and the guys showed me underneath I was amazed at how the rust was starting to set in.
A couple of days later the full underside and engine bay cleaned, rusty bits sorted and the full Dinitrol treatment done I couldn’t be any happier.
I would recommend this to anyone who loves there car.
I just popped in on while passing Johnston and the service and friendly manner from Mark and his crew were great.
It’s good to deal with a car nut even more nuttier than me.
Thanks for great service and value for money the before during and after photos are great to keep for my cars hopefully very long history.



Ivano Coia from Glasgow in January 2015

Just a short note to thank you for the Dinitrol treatment to my new import Eunos. Consider it the most sensible upgrade you can do to a MK1 MX5 if not the most glamorous and so glad I chose Preserve & Protect to carry out the work. Delighted with the work, service and all the advice, coffee not bad either.

Ivano Coia

Rory Force in May 2015

I wanted to protect my vehicle from the harsh Scottish winter road salt. After extensive research on the products available, I learned that Dinitrol was the product with the best performance and reviews.

I looked around for reviews of undersealing companies and learned of Preserve and Protect. From the outset, Mark was very honest and flexible to meet my needs, meeting me outside of working hours and working on the vehicle quickly.

Upon collection, I was delighted to find that Mark had carried out an outstanding job, sealing all areas that I could think of. The vehicle was cleaned and polished, leaving me to drive away as a happy customer. I will be bringing two camper vans to Preserve and Protect as I know I can trust Mark to carry out a thorough job.

Rory Force

Steven Grier in October 2015

Very pleased with the work Mark at Preserve Protect did – the guy knows his stuff – I don’t though ,however on looking under the van it’s a great finish, very neatly done and van back spotless. Mark is very professional – this comment is unprompted – just credit where its due for a professional job and a happy customer. Hopefully this will help a feeble US van last a bit longer on these sodden, salty shores.

Steven Grier

Matt Cooper in October 2015

Mark undersealed our classic Mexican Beetle (Poncho) which had recently been restored.  We were keen that the underside was treated so that the car will last for years to come.  Mark has done a great job and Poncho looks great with his new black underside.  The finish is great and the service was first class – Mark even ran me down to the station so I could get a train into work after dropping the car off. Mark really knows his stuff and is enthusiastic about his cars.  I would recommend Preserve and Protect to anyone who wants to protect the underside of their car.

Matt Cooper

Graham Johnston in December 2015

After several attempts to underseal my 2005 Shogun I finally admitted defeat. Great job by Mark and Sam. Very thorough and the vehicle returned in a lovely clean condition.

Pretty good cup of coffee too.

Great job, will recommend to anyone looking for this kind of work to be done.

Graham Johnston

Tom from Co Down, Northern Ireland in December 2015

Thanks Mark for a very professional job carried out on my Audi TT Mark 1.  Great advice and service and best of all the Result!  Thanks again for the DVD with the before and after pictures, such a difference!  

I would highly recommend Mark at ‘Preserve & Protect’. (Dinitrol Treatment)

P.S. Thanks you Samantha for the Coffees!


Stewart Douglas in January 2016

I found Mark & Sam easy to talk to regarding what I wanted done on the car – standard Dinitrol underseal & treatment of the fairly exposed, 13 yr old, power steering pipes.

All done very well, quickly & with a smile & photographic record to boot. One less thing to worry about on my weekend toy, MR2 roadster. Thank you, team.

Stewart Douglas

Larry Brown in January 2016

I wanted to thank you for the excellent work you recently carried out on my Jaguar XJR. The underneath now looks like a work of art and it is clear you have taken great care to get into every nook and cranny. I am absolutely delighted with the result.

While the car was in at Preserve & Protect you were also kind enough to carry out a couple of small ‘tidy-up’ jobs which other garages had overlooked. This was very much appreciated. It is always a pleasure to deal with a fellow enthusiast and I will return periodically to have my car inspected as per your instructions. Properly, brilliant service!

Larry Brown in January 2016

Dudley in March 2016

Mark and Sam’s experience and knowledge allowed me to keep a car I love. They were able to advise in an honest and factual way and their approachable nature made me feel relaxed about leaving my pride and joy in their hands.

I am very pleased with the end result and have certainly received a custom service.


Jim Stewart from Toyota in March 2016

My 22yr old Toyota was treated by Mark, with Samantha’s support, with the full Dinitrol  treatment; the result is impressive.

Mark’s attention to detail is much appreciated by me. All in all an excellent job.

Well done!”

Best regards,

Jim Stewart

Jonathan McCart in April 2016

My experience with Preserve and Protect has been nothing but a delight.

They have been very flexible regarding time slots and to work round my own personal working hours which made things run so much smoother. 

The job itself seems to have been a thorough job and I’d be very surprised if I had issues with the car in years to come.

The price was great for the time effort and service received.

Mark and Samantha did a fantastic job on my 2.4 Honda Accord, First class work, could not be faulted. 10/10.

Nicolien in July 2016

We are happy customers as our Landrover Defender got treated for rust and this has been done very professionally and with perfect customer service. We got well informed before, during and after the treatment. Our car is as new!

We recommend this company to everyone!


Carla in August 2016

Excellent service from Mark and Sam really refreshing to talk to folk who know their stuff. So pleased I had my car protected with the Dinitrol process. Also helped with run to and from train station. Great wee business, Thanks.


Pete in August 2016

Thanks for getting the TT done for me; and Sam, I very much appreciated

picking up my motor that was cleaner afterwards than it was when I left

it with you!

It was a full 11 hours of travelling up and back ( you see the

sacrifices your clients have to make just to get to you?) stopping in

Dundee for more fuel and a sandwich. Probably a good job, as a truck and

car were in a collision on my road home, with the driver being killed

just 20 minutes before I would have been on the scene, and literally 5

minutes from my front door. So, got my full “preserve and protect” that day!

Best wishes


Steve in August 2016

Mark and Samantha,

Just wanted to say a big thank you for the great job you did undersealing my MX5 last week.  Service was friendly, flexible and generally first class.  Thanks too for all the additional stuff you organised. That was really helpful.  I’d recommend you without reservation to anyone looking to extend the life of their car by having a thorough Dinitrol treatment.

Best regards


Gavin Fleming in August 2016

After searching online to find somewhere to underseal my MX5 as it was starting to rust a little. I came across preserve and protect, after a couple of friendly emails I popped over for them to have a look.

Couldnt of had a more friendly welcome! With a cup of coffee in my hand Mark popped it up on the ramp and showed me underneath. He explained the process of the undersealing. Turns out they are a fan of the MX5’s and gave me a ton of advise aswell as sourcing me a window regulator which I was looking for! Mark even managed to give me a run to the station to get home! All in all a great experience.

Gavin Fleming

Frank Bergius in October 2016

Just a big thank you for all your kindness, help and skill.

The Landrover 90 looks great!

Preserve and Protect in Johnstone have just completed an exceptional job on my 18 year old LS400.

I thoroughly recommend this friendly, fair priced service to anyone considering vehicle undersealing.

Thank you so much for the wonderful job that you have done on the Defender camper, we have shown her off to people and have already recommended you to others.


David Stewart in November 2016

Many thanks for the lovely job done on my old merc. My old car will stand a chance against the scottish winter now.   Your efforts to track down the underseal colour to match the original from the factory were particularly appreciated.  Very happy to recommend preserve protect to anyone looking for a top class under-sealing service.

David Stewart

Lee Carl Reginald Aubrey Garratt in December 2016

Tremendous service and exceptional workmanship, I cannot recommend these chaps highly enough. I drive an old vintage Jaguar, a rare site in Northern Scotland as such cars rarely see through the winters unscathed. Just one winter in Aberdeen resulted in panels rusted through and almost irreparable damage to the structural integrality of my prized car. Preserve & Protect not only dealt with all the existing rust and structural damage, they have ensured my car will survive the salt laden roads during the upcoming winter seasons.  

The protection the undercoating they have applied is already proving effective – not a spot of rust anywhere!!

I used Preserve & Protect following several recommendations and travelled over 600 miles to do so.  Their service is impeccable, professionalism and workmanship beyond reproach. If you have a vintage car in Scotland you’d be a fool to trust your car to anyone else.

Giacomo Marletta in January 2017

Mark performed a great job on my 2001 Alfa GTV V6.

From the initial contact via phone where he explained the process in great detail, dropping my car off and being offered a free run to the station, all the way through to collection, I felt happy he had the experience and care to look after my car.  

I feel confident my car is protected for years to come and look forward to the annual inspections.

Giacomo Marletta

Martyn Grant in January 2017

Mark has done a great job under sealing my Toyota Hilux.

All work was done to a professional standard using the correct products. I Highly recommend preserve & protect for treatment of vehicle chassis. Top job!

Ken Oliver in January 2017

Look no further peeps, P&P are the business; shear quality from start to finish.

I’m ‘old school’; been into motors all my life and love perfection. Mark and Sam have a great understanding of what people like me need, and they most certainly ‘tick’ all the boxes. Very refreshing to deal with, will most certainly be returning with other vehicles and will highly recommend to all my friends and anyone else sensible enough to listen. 

Finally, THANK YOU Mark and Sam for all your hard work. Very much appreciated.

Ken Oliver

Martin Coopland in January 2017

Preserve & Protect, great professional and friendly service from Mark and his team. From just having seen their workshop, I knew the work would be good and I was not disappointed. One Hilux that should last a lot longer.

Many thanks

Alistair Wilson in January 2017

Many thanks for such a great job.  The underseal looks like my campervan will last longer than me .

Alistair Wilson

Santiago in March 2017

Bringing my car from a much warmer country, I was quite worried about the Scottish winter. After much research I choose Preserve&Protect, and put my car in Mark’s hands.

Not only they did a thorough work, but also the quality and cordiality of their service was well above expected.

I am very pleased and can’t recommend it enough!


John Craig in March 2017

Preserve and protect did a superb  job undersealing my mx5.  I wanted to protect it from the Scottish winter, but had no idea about what products were out there or where I could get it done.  After some internet searching and checking out a few online forums, I gave Mark and Sam a call.  Mark explained the whole process start to finish and was more than happy for me to pay them a visit and check out vehicles before, during and after the process. 100% satisfied with the result and would highly recommend – I even got help and advice with another job that needed done on the car!  A totally professional service and these guys definitely go that extra mile.

John Craig

Sandy Sneddon in March 2017

Had my defender under sealed by Mark and very pleased with the service. From first contact Mark was quick to reply and was polite, friendly and professional. When I collected to car it was clear to see Mark takes pride in his work and has done a top class job. He is obviously very knowledgable and offers a great service. I would have no hesitation to recommend Mark to anyone. Thank you.

Sandy Sneddon

Mark in March 2017

Hi Mark

Quick note to thank you for your excellent professional and friendly service. Toyota pickup looks like new underneath (and you must have waxed it too) and will hopefully last far longer than Toyota sadly intended. I would recommend you and your business to anyone. Thank you John


James Mcculloch in March 2017

Top quality workmanship and attention to detail will be recommending everyone to take there car here for any undersealing!

James Mcculloch

Peter Gallacher in March 2017

I have just had my 911 treated by Preserve & Protect in Johnstone and can 100% recommend them. Absolutely faultless. On time, on budget, clean and super friendly.

Mark talked me through the whole process before I booked my car in and was deeply knowledgeable and reassuring.

This is one of those rare gems where a family business that really cares about what they do and ensuring that the customer is totally satisfied.

My car was spotless when it came back and the dvd of pictures during the Dinitrol process is certain to be of significant future value should I ever decided to sell.

If you have any questions about rustproofing in Scotland they are most definitely the people to contact.

Peter Gallacher

Peter Mackin in April 2017

Great service from Mark,car has been done in a timely fashion & was left gleaming in the sun with roof down waiting on me.

Wish I had known I could have had my oils & fluids done at the same time.Im very fussy who I have working in my car but I would have no hesitation leaving it with mark to do any work.

Nice chatting with mark & Sam this morning & see you for my oil /filter & all fluids soon. Cheers

Peter Mackin

Steve from Scottish Borders in April 2017

I have had  various Landrover Defenders over the years and key to keeping them for as long as possible is under-sealing. I have used Waxyoil previously and since moving up to Scotland looked to have my latest Landrover undersealed.

I found Mark at Preserve and Protect based in Glasgow and I am glad I did, was really impressed with the Dinitrol System . An excellent service from the initial call and enquiry, through to the actual work being carried out and then a great job done.

Communication and explanations of the work were clear and the team has done a great job so many thanks for helping in keeping what is now a collectors item, looking great underneath the vehicle ! And see you next year for the annual inspection.


John Ellis from Dundee in April 2017

“We’ve lost craftsmanship. We’ve lost connection. Tele-sales invade your privacy with a recorded message; you buy your things online because it’s cheaper; at Tesco you get your groceries scanned without speaking to a human being.

Into this dystopian world comes this guy Mark and his team. Excellence with a human touch. Friendly, competent and incredibly thorough. He doesn’t just do what it says in the tin, but goes way beyond that.

Dinitrol is a great product, but only as good as it is if applied properly. Check! And some!! As a ‘for instance’ the photos aren’t just crudely taken snaps but a DVD (I hope never to sell but if I do will increase the resale value for sure)! Car cleaned, free coffee and everything.

By the way to any MX5 owners out there Mark sure knows his MX5’s and is passionate about what he does (spread the word!). My thanks and endorsement. Well done.”

John Ellis

Matthew Welstead in April 2017

Preserve Protect were recommended to me recently by a fellow Land Rover Defender enthusiast and I must say I was very impressed by the level of service provided by the team.

As soon as I got in touch with Mark it was clear that he takes maximum pride in his work and he was able to fit me in very quickly.

Mark is extremely knowledgeable and talked me through the entire process in detail. Most of Mark’s business comes from repeat business and referrals and it is clear to see why. I would have no hesitation in recommending Preserve Protect – thanks again for the great job.

Matthew Welstead

James Cairney in April 2017

Exactly what I was looking for, meticulous attention to detail, fantastic job done in a few days.

Mark even had my tired alloys refurbed saving the hassle and time of me taking the car elsewhere.

I’m always dubious and over protective leaving my car with anyone but Mark and Sam put me at ease straight away.

I highly recommend Preserve and Protect and have already set a reminder to book in for my anniversary inspection!

I`m very grateful to you for getting this sorted before it got overlooked .

The car looks brilliant (as anticipated). Thank you for great job and for excellent service from you both.

Peter Branney from Edinburgh in May 2017

Thank you for doing such a great undersealing job for me.  You welded the holes and applied dinitrol treatment to the seriously rusty chassis of my elderly Land Rover 90 and gave it a whole new lease of life.

I’m extremely grateful for that. Not only did you do a fantastic job, but you handled it in such a professional and friendly manner throughout.  It was a pleasure doing business with you and I’m genuinely pleased with the result.

For anyone thinking of getting similar work done, I can thoroughly recommend Mark, Sam and the rest of the team at Preserve & Protect, Vulcan Works”

Alan in June 2017

Doing all my own maintenance and improvements to my Jimny,I’d seen the underneath of it enough times to know the only way to ensure it’s longevity was a comprehensive/thorough anti-corrosion application.Searching the Internet led me to Preserve&Protect,Mark and Sam exhibit to me the most important quality that I was looking for in a company that does this type of work,-quite simply they are car enthusiasts themselves and treat all the cars as if they were their own.

Listening to Mark and Sam enthuse about the stages of the treatment that my car was to undergo left me in no doubt that they were the company for the job.They understood fully when I explained the rust-prone areas on a Jimny that would require specific attention,which put my mind at ease and I would heartily recommend Mark and Sam as THE place to go should you be looking to have this done on your car.


Gareth in June 2017

Thanks for a very professional service. I’m now confident that my VW Camper will be protected for many decades to come.


Colin MacPhail in June 2017

Preserve and Protect done a tremendos job of undersealing my landrover Defender. Mark was very helpful, great service and I would highly recommend.

Colin MacPhail

Bob Shaw in June 2017

After initial email enquiry, with an immediate reply, a phone call was all that was needed to arrange a date and time to start the Undersealing Job. Price paid  was as per email quotation and very reasonable for the vehicle treated.

Friendly, efficient, Professional service from a Family Business, with attention to detail. I can thoroughly recommend Mark and Samantha at Preserve and Protect in Johnstone.

Bob Shaw

Ralphy Viterbo in July 2017

Mark, Thanks for sealing my defender, It looks like a spectacular and thorough job! Cracking work! It should keep the worst effects of battering up and down the knackered old farm track to my house at bay for a few years!

I’m very happy with the service, it looks ace! I totally love my defender and this will keep it in good nick for a few years longer.

Ralphy Viterbo

Dave Connelly in July 2017

Outstanding service on my Mustang. Mark walked us through the process and explained all the options on which treatment and what the benefits were etc. Price quoted was price paid. DVD of before and after showed the limited coverage that had been applied by the factory, the after pictures couldn’t be more different.

Family run, integrity, honesty and a down right fantastic job. Highly, highly recommended.

Dave Connelly

Stephen in July 2017

Thanks to Mark and Sam for the 5 start work carried out on my 2011 MX5. I can’t praise P&P enough for their professional approach to working on my car, treated as if it was their own. If you want to have this type of treatment carried out on any vehicle I would highly recommend Protect and Preserve for their attention to detail and talking you through the whole process. As others have said it is refreshing to see the honesty and integrity from this family run business.

Thanks again.


Gabriel from Aberdeen in July 2017

I decided to get a preventative underseal done to extend the life of the M coupé after multiple issues with brake lines (and brackets) corrosion during the 11 years of her life in Abeedeen- very common issues. After much searching, Preserve and Protect is the name that popped up multiple times. I read the reviews and decided to contact Mark. 

Mark strike me as someone that is very passionate about his cars through the conversations we had (be sure to check out his awesome Minis!). He explained the process of rust treatment, undersealing and offered free annual check-ups on the underseal.

The before and after photos are striking. Mark managed to do some minor tidying up on top of the underseal which I really appreciate. 

This is a job done by enthusiasts for enthusiasts. Mark and team has done a good job. My fellow enthusiasts, if you’re going to keep your car long term or want to improve it’s resale value, look no further!  


Morgan in August 2017

“I have no hesitation whatsoever in recommending Preserve and Protect. From the very first email Mark and Samantha were a pleasure to communicate with and responded quickly to enquiries, they were also welcoming on the day and really understanding and accommodating to my needs. It’s rare to find a place that treats your car like it’s their own, no matter what the car is. The quality of the work is very high, and the process is thorough. It was well worth making the trip and I plan on bringing another car for treatment in the future.”


Stewart Gibson in August 2017

I was looking for the best protection possible for my R51 Pathfinder and from various reviews from different owner’s club forums, I decided that Preserve and Protect would be the best.  

Mark was very helpful in explaining the process and is also passionate about the work that he carries out.  He is also a true car enthusiast, happily chatting about cars which gives you the re-assurance that he will give your car the time, care and attention required, no matter what the car is.

The application was very thorough and all cavities, crevices etc were fully treated.  I would definitely recommend Preserve and Protect for anyone looking to extend the life of their car.

Please accept a short note in thanks for the works completed on my old 3 series.

I am delighted with the preparation & finish and you are absolutely right – I do believe the road noise is reduced as an added benefit.

Really pleased to have had this done and will recommend your firm wide & far – BR PG

Stuart Hepburn in September 2017

Thank You so much for the outstanding job you did on my Mazda 3  Extremely rare to find a family run business that actually cares about the work they do, reputation and after care. 

I wouldn’t go anywhere else, you have a lifetime customer and two more cars coming your way soon!

Thanks for everything Mark – and baby Arran loves his owl, Mum and baby doing well.

If you’re looking to have your vehicle preserved and protected, look no further! I’d like to offer a huge thanks to Mark and the team for their outstanding work undersealing my Nissan Skyline GTR.

I cannot recommend their business highly enough – Mark went above and beyond to ensure that the service I received was second-to-none.

A Reid in October 2017

I had my Mx-5 ND undersealed, they done a fantastic job and I’m very satisfied with the results. I was talked through the full process, as well as being giving other advice about how to take care of my vehicle by Mark.

If preserve & protect were a restaurant they would have a Michelin star for excellence.”

I was extremely impressed with the work Mark and his team did on my beloved Suzuki Jimny.

I had tried to do some undersealing myself but it clearly required a professional job and the difference is enormous: it looks fantastic and I now have real peace of mind.

Many thanks!

Fantastic service, extremely friendly and helpful.

Mark took us through the complete procedure, explaining all aspects.

Would highly recommend this service to anyone contemplating getting their vehicle undersealed.

Once again a big thank you to Mark and all his staff.

I recently collected the second car that Preserve and Protect have done for me. The fact that it is the second car should be indication enough that I was very happy with what was done with my first car.

The first car was an almost new MX5 RF and the second was a 17 year old MR2 Roadster. So, I’ve had both a new and quite an old car done by them.

I heard about Preserve and Protect through recommendations from members of the respective owners clubs for these cars.

The whole process is very straight forward from a customer’s perspective. I contacted Mark via the Internet and arranged to get my car done.

I live some 150 miles from Johnstone so it suited me to drop the car off on a Saturday morning and collect it the following Saturday.

I believe that the process typically takes about three days, so leaving the cars for the whole week made sense and fitted in with my work commitments.

Mark and Sam are very friendly people and very good chat.

They make you feel really welcome.

They are obviously genuine car enthusiasts and very knowledgeable about what they do.

They talked me through the process and it was very clear that a very thorough job was going to be done. This is no quick “get it in, spray it and get it out” job.

A lot of preparation takes place involving taking out wheel arch liners, masking parts up and so on.

The rust converter is applied and left to do its job for 24 hours or so before the final protection coating is applied.

On collecting my cars, it was obvious that a proper job had indeed been done.

From what I could see at the time, everything underneath looked black and, now that I’ve been under the cars myself, everything that needs to be coated has been – very thoroughly.

With the older car, I also got a DVD of pictures showing before and after and the underside looks amazing compared to what it did beforehand.

Although the process isn’t cheap, it is value for money. A lot of time and effort goes into it and the materials are also proper Dinitrol products.

I am confident that both of my cars have been thoroughly protected and Protect and Preserve offer free annual checkups and repairs during the warranty period.

I know a number of people who have had their cars done and everyone I have spoken to has been happy with the result.

I have also happily recommended Preserve and Protect to other people and will continue to do so.

“Top job done on the auld astra , by a top man . Well done mark & the team.”


Linda in February 2018

“I had my Defender 90 undersealed by Preserve & Protect about a year ago and was extremely impressed with the efficient and professional service offered. My Defender returned to Preserve & Protect last week for its free yearly inspection which involves removal of the wheels and thorough cleaning of the underside of the vehicle. I am delighted that the undersealing process has undoubtedly done its job. This prompted me to put my MX5 through the same treatment. Mark and his staff are a pleasure to deal with and handled me and my vehicles with care and respect. I can highly recommend the undersealing service offered by Preserve & Protect.”


Derek Husband in March 2018

“Thanks to Mark, Sam & Dylan for the excellent service and for the work done on my car.

I approached Preserve and Protect following several recommendations from other owners within the owners club.

Preserve and Protect are fairly local to me, being about 17 miles along the road, but some of the owners I’d heard from had travelled much further.

This was all encouraging. I filled out the webform with an initial enquiry, and was pleasantly surprised to get a very quick same day response. After a further email, I arranged a visit to bring the car in for an initial inspection.

I was given a warm welcome by everyone, and I was brought into the office for a cup of coffee and a chat to explain the process and the products used.

The car was put on the ramp for an initial inspection, and once finished I booked the car in and ordered the optional extra photo pack.

I collected the car last week, and I am delighted with the results and the photos. Communication was great, from initial enquiry through to completion of work. The work was completed to schedule and budget.

Preserve and protect were a pleasure to deal with. Thanks again”

Ian Haldane in March 2018

I’d just like to thank Mark and his staff for the work they carried out on my pride n joy (1969 Pontiac GTO) From my first contact to completion, I can only say their friendly service and fantastic workmanship has been second to none.

My car came from a dry state in the US and now it’s prepared for the worst our Scottish climate can throw at it! Thanks again.

Mike Connor in April 2018

I am writing to congratulate you and your team on a first class service.   I had assumed that rustproofing was standard on modern cars but this is clearly not the case.  For my 6 year old Subaru Sti there was already early rust in key areas which would have led to expensive repairs in the future.  

Your treatment was thus a “stitch in time” at a very reasonable price.  I would unreservedly recommend your service to other potential customers.

Campbell in April 2018

Many thanks for the great job you have done. Very professional business and would not hesitate to recommend to other car enthusiasts. Regards


Douglas Wilcox from Galloway in April 2018

I have just bought a new Mazda MX-5 Mk4 which I intend to keep long term.

Having seen the rust problems on friends’ older models, I was keen to get it under sealed straight away.

I did some internet searches and found nowhere locally in SW Scotland.

Then I found very positive reviews of Preserve&Protect.

Johnstone is 5.5 hours away by public transport but any concern about the logistics of leaving a car there were put at ease by Mark’s rapid email responses to my enquiries.

The quoted price was higher than that paid by friends for 1 day Waxoyl treatments but Mark explained the process saying on a new MX-5 it would take 3.5 days and use Dinitrol.

I decided to travel to Johnstone and having met Mark and Samantha and been shown their neat and tidy workshop, I had no doubt that I had made the right decision.

Mark is a real car enthusiast and knows his motors inside out, including MX-5s.

He spent a long time giving me tips about what to look out for especially where to look for some difficult to find drain holes to keep clear.

Mark is also not touting for unnecessary business.The work on the MX-5 was completed bang on time, which is very important if you are travelling a distance to pick the car up.

The car was spotless and the DVD with before and after photos showed a very thorough job had been done.

I was shocked that, as delivered from the factory, much of the underbody appeared to have only a coat of white primer on it (it is a black car.) The quoted price was exactly what I paid and I consider it excellent value for money.

I have no hesitation in recommending Mark and his professional team.

Douglas Wilcox

Paul in April 2018

Thanks for a great professional job done on my Clio.

It was good you hoisted car up and showed me under the car and talked me through the process you do.

Also thanks for keeping in contact via e-mail to show me pictures of my car before and after.

I would happily use you again and recommended you.


William Robertson in April 2018

I found this firm to be very good from the moment of first contact until collection of my Motorhome.

The whole process was explained to me on first contact and I was sent photographs of the progress throughout I am very impressed by the quality of work and the price.

Thank you Mark and staff at Preserve and Protect William Robertson – April 2018 / Fiat Ducati

David Wright from Aberfeldy in April 2018

Many thanks for a really first class job on my car.

I was particularly impressed by being taken through the process beforehand in great detail and shown examples in your workshop of vehicles at the various stages of the treatment.

Also the evident care that you and your team take not to contaminate areas that were not being treated.

The ‘before and after’ DVD you supplied when I collected the car was very informative and could be very useful to show any prospective future buyers should I ever think of selling the vehicle, much less likely now that I’m reassured that it is protected to a very high standard!

May I also congratulate you on the observed general morale of your team. The guys I spoke to could not have been more considerate and respectful.

Surely a testament to your excellent leadership. Thanks again and I will certainly return the car for the free checkup in a year. Kind regards Dr David Wright Aberfeldy

A big thanks to Mark and his staff for the work done on my Subaru Impreza 330s.
I can’t fault his customer service or meticulous approach to carrying out the job.
When I first contacted Mark he explained the process in detail and that I would be kept updated regularly with pictures at each stage.

As promised, I received plenty of pictures showing the car before, after cleaning and when complete.
Mark and his staff are very friendly and informative with nothing being too much trouble.
He was very busy at the time but I never felt rushed and every vehicle he does gets the same care and his attention to detail.

I would highly recommend Mark and his team at Preserve and Protect and wouldn’t hesitate to use him again.



James Callaghan in May 2018

I bought a 9 year old Ford Transit to convert into a campervan. Like most Transits of its age it was getting pretty rusty underneath so I started looking into how to repair the existing rust and prevent it from getting worse. I spent hours watching tutorials on Youtube, even ended up dreaming about lying under the van scraping rust with a wee wire brush and realised I would never be able to do it on my own.

So I went looking for a garage who could do it properly and found Preserve & Protect. In the free inspection, Mark put the van up on the lift and showed me everything as he went over it – including finding a really poor rust repair “weld” a previous garage had done with scrap metal and silicone sealant. I booked it in to get it done there & then, was advised it would take 7 days but it was done in 4! Along the way they found a half dozen rust holes that someone had tried to hide with silicone – each was photographed so I could decide whether to get welding done by their in house ex-RAF welder, which I did.

I got photos of the completed welding, and then more photos of the finished underseal. Mark and his team are total enthusiasts, take a huge amount of pride in their work and the results are flat out awesome. If more vehicles went through their garage there would be far fewer getting scrapped.

James Callaghan

David Barbour in June 2018

Just to say I was very impressed with the level of service in connection with the underbody treatment on our car. The car was given a full check-up for possible treatment and a quotation supplied. All work was carried out to a high professional standard including the alloy wheels that looked like new after being refinished. Everyone was friendly and approachable with a high level of customer interaction. Based on my own experience I can recommend Preserve and Protect.

Alan in June 2018

Been looking at places to take my Evo for a while, came across Preserve and Protect, read the reviews and thought a would pop down and let Mark and the team check over the car. On arrival was greeted by Mark and Dylan and from there the car was put on the ramp and the boys took me through the process and allowed me to see the condition of my car (had seen better days).

The car required some welding which was no problem said Mark after a cup of tea and a chat with the lads I left the car in their capable hands! The car required new sills and some welding on the boot floor and chassis. From start to finish I received multiple photos to document the car’s repair process, loved being able to see the transformation as it happened!

All I can say is Preserve and Protect went over and above my expectations. Nothing was a hassle and once the car was in the garage Mark and the team brought my Evo 6.5 Tommi Mackinen back to life!

Once the car was complete Mark offered to take it for its MOT which was a great benefit to me, as I had to transport the car over on a trailer. On the return leg I got to drive it home . If you are looking for a 110% job Preserve and Protect is the place to go. Once again many thanks to Mark and his team!
Cheers Alan

John in June 2018

Hi folks,I have just got my 2010 Defender 90 back after having had the preserve & protect treatment. I did lots of research into the best treatments and then who I felt would do the best job completing the treatment. From the very first contact until my buggy was returned today, the service was always very professional and very friendly. Mark is a pleasure to deal with and clearly takes pride in his work. I would highly recommend Preserve & Protect to anyone with a vehicle they want some tender loving care applied to. I will definitely be back for follow up checks and future treatments as every box was ticked for me. Many thanks to Mark and his team. Till next time. John.


Philip in June 2018

After reading up on various forums on how vulnerable MX5’s were to rust due to undersealing issues, I decided to get my MK4 treated.

The next big decision was which product to go with – Dinitrol or Waxoyl. Again, it appeared that Dinitrol was the superior product. I wanted my car treated professionally so yet more research led me to ww.preserveprotect.co.uk

They responded quickly to emails and phone calls, and since they have been established a few years they know what they’re doing. I dropped my car off at their premises and collected it a few days later. I was kept up to date with photos of the progress.

As part of the deal you can take your car back annually for a check, and any defects in the seal can get repaired. Highly recommended

Philip .


John Dryden in July 2018

Whilst I was away walking last week the Jimny was treated to some rust prevention. Fully cleaned, Rust convertor coated with Dinitrol and all the nooks and crannies filled with 2 applications of cavity wax. Engine bay also coated in a clear wax. Hopefully help see it through plenty of salty winters. Thanks to preserveprotectundersealing.

Peter in July 2018

Thank you for looking after my car when it was in. Mark did everything required to get the car it’s MOT including what another garage described as “Terminal” welding. No fuss, no humming and hawing just great service oh and he also gave it the best de-rusting and undersealing in the country. My x-type is future proofed for the next few MOTs.
Many Thanks,


Alfie in July 2018

Amazing team at preserve and protect took my civic to have some rust holes welded and then under sealed. The guys kept me informed throughout the whole procedure brilliant service first class! Would defiantly recommend.
Thanks again,

Many thanks to Mark and his team for the great job they did in undersealing my Mazda Bongo Campervan.
The level of service, I received, from the initial inspection to the completion of the work, was most impressive and sending me photos showing each stage of the process was greatly appreciated.
I would recommend Preserve and Protect to anyone looking to have this type of work done on their vehicle.

Andrew Cook

Murdo Macleod in August 2018

I am currently going through a ‘refurbishment’ process on my Vectra and had decided that before any cosmetic works were started, it would be best to get the underside inspected and protected.
A quick search on the internet came up with one or two places that I could use however, preserve and protect was the most appealing, mainly due to the fact that they use Dinitrol, a superior product to waxoyl. The reviews left by previous customers are all very positive and also very similar. I telephoned p&p and Mark, the owner spent time ‘educating me’ on the entire undersealing process before inviting me along for a free inspection there and then which I accepted.
From the start I was made to feel very welcome, offered a cup of tea and even some of their goodies that they were going to have for lunch!
Mark’s enthusiasm for what he does is obvious, it is very refreshing. Mark realises that regardless of what car is brought to him, it is the customers pride and joy. I was sold and more than happy to leave the car with them for the full underseal.
Whilst the work was being carried out I was sent multiple photos of each stage, before, during treatment and after completion. This is a great addition to the service and a very handy one should a future buyer want to see the car before the undersealing. It also proves that they do in fact carry out the work at each stage.
I particularly like that the underside of the car is descaled, fully steam cleaned and then ‘rust converted’ before any underseal is applied. Preparation is key to any job and they do just that.
I highly recommend Preserve & Protect to anybody who is currently thinking about protecting their pride and joy.

Graham Mckirdy in August 2018

I wanted to express my thanks to you all.
I was impressed with the treatment from you all from the day I popped over a few months ago for my inspection and from the minute I dropped the Land Rover off was kept up to date with photos of the underside of the vehicle throughout the process.
I would not hesitate to recommend you guys to anybody thinking of having their pride and joy treated to an undersealing.
I made the mistake of having my old Discovery waxoyled from what I thought was an approved  garage but was to later find out that the process wasn’t carried out properly and the inspection guarantee not honoured.
The garage only had the vehicle for 10 hours to clean and treat the chassis, I should have known better.
Your updates over the 4 days the vehicle was in reassured me that the treatment was being done properly and now that’s its done, one less thing to worry about.
We are all too quick to complain about shoddy service and don’t really bother to acknowledge good service, so once again thank you.

Steve Henderson in August 2018

A month ago after talking to Mark, I left my Toyota Granvia Campervan for two weeks whilst I headed off to the Shetlands to work for a fortnight. I had earlier found Preserve & Protect on line and contacted Mark by email. His prompt and excellent customer service ensured that the work came his way. My ‘Granny’ needed a thorough scrape and clean underneath and a good underseal applied. It also needed some welding to the jacking points to the front.

Having collected the vehicle a few weeks ago, I just want to say what an outstanding and professional job that Mark and his team have done on the Granvia. From the outset, all my questions were answered which included sorting the welding and refurbishing the spare wheel. Working away, I was kept updated and plenty of before and after pictures supplied. I can’t praise P&P highly enough, for work which has probably extended the life of the Granvia by a good 5-10 years.

Thank you to Mark and support team once again for a superb job!

Best wishes

Hello, Excellent service and work from Mark and his team. Mark was brilliant from our first phone call. I am 100% satisfied with the result and would highly recommend his work.

Mark detailed the steps they will do to underseal the car, the parts to be removed, the tools used, the coating process with a tour of the garage showing other car in various stages. Mark is very  professional and available, his communication is up to date using it to demonstrate the work progress on my car.

I did quite a bit of searching on the web and visiting garages around Glasgow. I eventually settled for the Dinitrol Underseal and found “Preserve & Protect Vehicle Undersealing Service” that looked good. On the first call Mark was a pleasure to deal with and clearly takes pride in his work. Taking the time and engaging.

The reviews are true to this company. I will definitely be back for follow up checks and future treatments. Many thanks to Mark and his team. Till next time. Gregory, Mercedes e320.


Sam McBride from Edinburgh in September 2018

I had previously had my 1988 Range Rover waxoyled and therefore knew it to be in good condition. However, I wanted to ensure continued protection during winter and off-road usage. I therefore made an initial telephone enquiry to Preserve & Protect during which I was impressed with Mark’s description of his Dinitrol process. I therefore arranged to visit him to allow a more detailed assessment of the vehicle and a discussion of the options for treatment. Knowing that preparation and attention to detail were critical, I was suitably impressed by Mark’s overall approach, knowledge and facilities and both the time and effort required for the visit were certainly worthwhile.
A full Dinitrol treatment, including the options for hard finish to axles and differentials and clear treatment to the under-bonnet area was subsequently agreed and carried out in May 2018. In my opinion, Mark and his team did an excellent job. A follow-up inspection after 12 months is included and I am confident that this will be approached with the same care and attention.
I have therefore no hesitation in recommending Mark, Samantha and their team to anyone wishing to having a full and proper job done.

Harry Saunders from Skye in September 2018

My last car, a lovely 06 plate MX5, hadn’t been undersealed and finally succumbed to the tinworm earlier this year. I had enjoyed driving the car so much that I couldn’t imagine anything else, i.e. anything sensible, as a substitute. The metal on the rear subframe had delaminated so much that it felt like Weetabix. Big holes in the sills and a load of other problems sealed the car’s fate.

Armed with the knowledge that Mazda, in their seemingly endless quest for weight saving, only put the merest whiff of paint on the underside. I purchased a 2017 MX5 with just 200 miles on the clock. I knew that the underside would need protection, so, after a fair bit of research on the internet I came across Preserve & Protect.

I stay on Skye, so a trip down to Glasgow was organised. Johnstone is a good bit further than I would normally travel for something as important to the longevity of the vehicle. I suppose that I could have gone to any number of garages, and have the underside done with a gallon of Waxoyl and a paraffin gun, but I wanted to have the job done properly.

As with other testimonials on this website, I am as pleased as punch with the outcome, and I would like to thank Mark and his team for their obvious enthusiasm for what they do.

Thanks again,

Harry Saunders

Andrew Menzies in October 2018

Mark and his team are just fantastic. I was looking to get my Maserati undersealed for winter and Mark talked me through the whole process and was able to refurbish my wheels via one of his contacts in addition he also provided a contact for paintwork should I require it.

Mark keeps you up to date with progress via WhatsApp, sending pictures through of the car at various stages and in my case I needed a small patch of welding done so he sent through a picture of the area to be welded and the cost (which was very reasonable indeed).Having put my car in for some servicing and MOT a few months later the garage commented on the fantastic job that Mark and his team had done.
The work Preserve & Protect have completed is second to none at a very good price, I would highly recommended their services and I look forward to visiting again in a year for a check as well as bringing another vehicle in for undersealing.

Work carried out:
underside and engine bay sealed
small spot of welding
Wheels refurbished (to an excellent standard) by a company Mark deals with

Thanks again to everyone for the work put in and for the excellent customer service.

Peter Gallacher in November 2018

Decided to give the Fiat Ducato Pilote conversion campervan a life extension and after doing an Internet search and speaking with Mark, I opted for the full underbody and engine bay Dinitrol treatment.

A full set of underbody photos, before and after treatment was provided as the work progressed.

On collection after 4 days, was happy to see a very tidy professional job had been done, with all the supporting documentation to hand.

In fact, Mark went one further and fixed a long-standing problem I had with the rear mud-flaps, at no extra cost.

Am pleased with the end result and wouldn’t hesitate to recommend Preserve and Protect.

Peter Gallacher

Ken Hay in November 2018

Thank you so much for doing the undersealing on my Land Cruiser. I’m glad I got it done when I did: As luck would have it the gritters were out spreading at the weekend and it was very satisfying to know that there is a thick layer of Dinitrol keeping the corrosive salt at bay.

I am very impressed by the comprehensive service provided by Preserve and Protect and would recommend Mark and the team to anyone keen to give their vehicle the best long term protection.

All the best.

Dr Angus Mackay in November 2018

I recently entrusted my cherished Jaguar XKR 4.2 -S to Mark and his team in Johnstone for Dinitrol rust-proofing. This treatment, a refinement on Waxoyl, has been highly recommended in Jaguar magazines, but of course the final results depends as much on the thoroughness of the preparation and application as the chemical itself. I am delighted to say that the whole procedure at Preserve & Protect could not have been more satisfactory. The car is meticulously prepared, all under-panels removed, even the rear light fittings, all surfaces thoroughly cleaned and dried before applying Dinitrol and allowing it to cure. Photographs were taken at each stage and sent to me by e-mail. My car was spotlessly clean inside when collected. Mark is a delightful chap who clearly loves cars, and I can highly recommend the whole experience to anyone who cares about their car.

Jamie Colgan in November 2018

Can’t be any happier with the work that Mark and the team done on my LandRover. From the day I enquired about the treatment to the minute I picked it up was very professional. All questions I had before hand were answered promptly and any doubts put to rest. I was kept updated throughout the whole process with pictures sent via WhatsApp so I could see it all being done from start to finish. I now have peace of mind that my vehicle will have protection through out the winter months and with a team like Marks a place to trust for every winter here after. Thank you Mark, Samantha and the team for what I can only say as a job well done. Great service, Great team and great value for money.

Nick Pender in November 2018

Jim in December 2018

The day started early in the correct way. Cuppa, biscuits and a discussion with Mark on how we would put the world to right.
Next was a guided tour round the various vehicles in the workshops showing the various stages of the preparation and protection process. Next was an educational Monday morning trip back home that involved four trains and a bus.
I was kept fully informed of progress on the E Type and this was backed up with photographs of the various stages. The photographs showed some nooks and crannies that I had never seen before. Interesting.
The return journey to Johnstone was less hectic as it was a weekend journey and not at peak travel times.
Mark had the E Type on a ramp and pointed out the various areas that required close attention during the work. I had chosen the Platinum Grey final coat. This shows up the underside structure of the vehicle better than the black and also sets quite hard. From my first phone call to collection of the vehicle, Mark and his dedicated team were first class and very approachable.
I have no qualms about recommending them for your vehicle and I will be having two of my other vehicles treated in 2019.
