Undersealing a car can extend its lifecycle. It is essential for rust protection, especially for car brands known for their susceptibility to corrosion. Using Dinitrol is the most effective way to do this. We are a top-rated Dinitrol treatment centre. We want to ensure your vehicle gets the best rust proofing and corrosion protection possible.
First, we will assess your vehicle against the vehicle grade sheet. To do this, we welcome you to book a FREE vehicle visual inspection, which takes approximately 20 minutes to complete.
During the inspection, we will be able to gain access to assess the current condition of the vehicle against the Vehicle Grade Sheet detailed below. We’ll identify any weak areas or concerns and inform you about the best treatment and rust-proofing products for your vehicle. This includes checking for loose rust and rust holes, which must be addressed before applying any underseal.
Our staff will be on hand during the inspection to answer any questions you may have. These staff members include fully qualified and experienced Rust Prevention Specialists, Mechanics and Fabricators.
Vehicle Grade Sheet:
Completely Rust Free or minimal amounts present. This would suit Brand new vehicles or Fresh Imports.
Surface rust is present but regarded as minor.
De-lamination Identified – The Separation of rust layers.
Heavy surface rust is present on the underside/arches/cavities and welded seams.
Severe rust Issues recognised & advised as uneconomical to repair.
Car Undersealing Treatment Day:
When you arrive, we will confirm all contact details and how you wish to be contacted on the day and beyond.
Did you know?
We photograph every stage of the car underseal treatment, from disassembly and masking to the results. You will get regular updates of progress and end up with approximately 60 Images. This is a fantastic record for any car file and a great way to document its time with us.
First, we remove all the wheels, arch liners, and underbody guards from the vehicle. Then, it is fully masked up and provided with a fresh protective car wrap to protect the paintwork.
During this process, we pay special attention to exposed areas, such as the chassis and wheel arches, which are vulnerable to water, dirt, and corrosion from road debris.
At this point, we are able to give an accurate grading of your vehicle’s current condition. The grades are from 1 to 5, with 1 being like a brand-new vehicle and 5 having severe rust Issues. This helps us gauge what treatment methods to use to ensure the most longevity and best results.
We need to Assess the appropriate vehicle grade and preparation work that will be required.
In some cases, if the grade is between 3 and 5, some welding may be needed. Additional tools and equipment may be needed to fully prepare the surface.
Corrosive salt, commonly found on UK roads during winter, poses a significant risk to the undercarriage, necessitating the application of protective underseal treatments to create a barrier against these harmful elements. Applying car underseal or cavity wax can be a more economical choice to avoid costly welding repairs in the future.
We may need to remove additional parts, such as bumpers, exhausts, prop shafts, and suspension, to gain better access and give better treatment. If this is necessary, there will be an extra charge, but we will discuss this with you.
Next, we need to descale and fully steam clean the underside and arches of the vehicle using a degreaser. From here, we will treat any rust with a rust convertor, which will be left to cure overnight. Depending on the severity of the rust, we have various grades of rust convertors and inhibitors to use.
After the rust converting development time, we will inspect it and ensure a second application of the rust convertor isn’t needed. If it is, we will apply it then.
We can progress to the priming and spraying stage if all is well. Available colours: Black, Clear or Bronze. The primer and spray are left to cure for 24hrs. (Extra Heat can be applied if needed)
Did you know? We also carry out a Raptor service, which is a hard epoxy paint that can be tinted to any colour. Check out our website for a full rundown.
At this point, we carry out a double application of cavity wax injections along with rust inhibitors into all cavities, chassis, cross members, and box sections. We want to ensure you have full car underbody protection, rust-proofing, and prevention treatments. This is especially important for modern vehicles, as they are also susceptible to the rusting process due to factors like moisture infiltration and road salt.
At Preserve & Protect, we make sure we don’t miss a thing. We have spray diagrams for most vehicles to fully ensure we maximise and plan out every area of rust proofing and welded seam. Some makes and models can have hidden or hard-to-reach areas.
Our experts will now fully examine the wax finish to ensure consistency and texture before reinstalling the arch liners and underbody guards.
Inspecting the wheel arches during this process is crucial, as they are vulnerable to rust and corrosion from harsh road conditions and require appropriate treatments to maintain their integrity.
All protective coverings have been removed, and final checks will be carried out before the wheels are put back on.
Collection and Handover Instructions:
You will be given a time when your vehicle is ready to be collected. We will have fully sanitised it before handing it over. We will then issue you with full instructions on how to best care for the newly treated underside of your vehicle. Expect to have a full report on what corrosion and rust treatment was used and to see the amazing results of your newly protected vehicle.
It doesn’t end there—we offer Free annual Inspections! Just bring your vehicle back to us, and we can fully inspect its overall condition after each year. If your vehicle’s grade is poor, we may ask to see it back sooner to continue with the rust-proofing service.
Over the years, we have gained a lot of knowledge regarding rust and rust prevention. We know what combination of products to use for brand-new vehicles, vehicles in average order for their year/age, and what’s best for longevity. This includes understanding the specific needs of imported cars.
We know each car is unique, and its condition depends on several factors, including its age and usage. At Preserve & Protect, we are able to put together a personal package individually catered to both the owner’s and the vehicle’s needs.
The traffic light system below helps us determine what treatment will best benefit your car. Each vehicle’s condition is individual, and some will require more preparation than others. Generally speaking, the more time spent on your vehicle, the higher the cost to repair it. Applying underseal can be a messy and challenging process, but having your car undersealed is crucial to protect it from rust & corrosion, especially in harsh weather conditions.
*** Please note: Work will only be carried out with prior agreed permission. ***
Red : Overall very poor condition with heavy deposits of rust. 6+ hours of preparation.
Amber : Overall condition is okay and in average order. 4 – 6 hours preparation.
Green : Great overall condition with minor surface corrosion. 1-3 hours preparation.
We can provide estimated quotes and bookings via our website, Facebook, and Instagram, in person and via telephone. Our bookings team aim to respond promptly and will happily work your vehicle’s treatment around your busy lifestyle.
