Waxoyl V Dinitrol

About our Undersealing Service

Most car enthusiasts will agree that one of the most important factors of owning your vehicle is rust prevention, particularly for older cars and classic cars too.

Our UK weather provides the ideal weather for rust on your vehicle nowadays.  With our ever-increasing harsh winters bringing rain and snow it is a perfect time for your vehicle to start getting rust on it.  We also find our roads being treated with more and more salt to combat these bad road conditions too.  Therefore, you need to think about your rust prevention for your vehicle

Here are a few pros and cons of these treatments for your vehicle and why rust prevention is very important to your vehicle. What is the difference between Waxoyl and Dinitrol?

  • Waxoyl is a wax type and Dinitrol is a grease type of treatment. The wax type of treatment has white spirit as the carrier and the grease type of treatment has mineral oil as the carrier.  It will come down to personal choice which one you chose for your vehicle. 
  • Dinitrol will get into the nooks and crevices of the vehicles bodywork to give good rust prevention. It also has a rust inhibitor to counteract any surface that the rust encounters giving you a good rust prevention.
  • Waxoyl is an oil and water mix and therefore it will never cure. So hot days it will continue to drip out of any of the holes it was applied to on your vehicle.  It will also give out odour from the oil.
  • There is also no smell from this application of Dinitrol as the solvents are aromatic. When the wax and solvent vanish, it leaves only the wax. This will expand according to the temperatures.
  • Dinitrol also leaves a skin when applied onto your vehicle and stays soft underneath it allowing it to self-heal in temperatures that it is subjected to. This means that it will self-heal over small stone chips and scratches too.
  • Dinitrol is far easier to apply than Waxoyl as it has been shown that Waxoyl can be affected by the changing weather.
  • In a report that was carried out it showed that Waxoyl doesn’t seem to penetrate any significant amounts of rust whereas Dinitrol did fill in those gaps.


Rust prevention is a rewarding job and one that everyone should think about that owns a vehicle, especially those that are an enthusiast about their classic car.  It is part of ongoing maintenance for your vehicle and an important step in classic car restoration.

Rust prevention treatments shouldn’t be applied onto damp or wet surfaces.  Early autumn is the best time to apply your treatments as that is when it is more than likely to have fine weather and have a few dry days to complete your treatment.  The alternative is to use a specialist rust prevention facility.
