MK3 MR2 Undersealing : Dinitrol

20th May 2019

Corrosion in cars is a serious issue. Not only can it be costly from a financial standpoint, but it can also be extremely dangerous by compromising a vehicle’s
safety. Corrosion will inevitably shorten the overall lifespan and value of any vehicle. So, it’s important to know exactly what rust is and how it occurs on your car. When the iron contained within the steel panels of your car and oxygen mix with air or water, rust begins to develop. In time, rust with overwhelm the iron content and begin to disintegrate. If dirt and moisture build up on the underside of your vehicle, then rust & corrosion may occur. As this part of the vehicle is difficult for the everyday owner to view, it isn’t easy to see whether corrosion has begun. If it has, and it’s allowed to build, then ultimately the underbody strength will be diminished and the vehicles safety may well be compromised. Not all car corrosion comes from outside of the vehicle. In fact, a considerable proportion of vehicle corrosion develops when moisture build up inside the cavities of doors and other panels. The metal in these areas tend not to be subjected to anti-corrosion protection and as such are open to moisture build up, which in time, will likely develop into rust if not treated.

Dinitrol products and the application procedure are designed to prevent future rust and not to fix excessive rust if present. Whilst undergoing the procedure of applying the Dinitrol this MK3 was after new subframe, KYB shocks all round, top mounts, bump stops, Tien S-Tech springs, Superpro full suspension bush kit, removal of the pre-cats, a new Cobra exhaust fitted, Clutch, gaskets and service items. After all was said and done a four wheel alignment was required to get the most out of all the suspension work.

Some pictures through the process below. A pleasing site to see all the new parts fitted. Owner Barry was pleasantly surprised by the Roadsters new feel and the piece of mind the Dinitrol provides, after all, what good is new suspension components if in a few years time there isn’t anything to mount them to after rust has had it’s way.

This may not look like much but in a few years it would have been a much sorrier state.

Out with the old

Ah much better!

And that rust from before, no more!
