Undercoat sealer removal

I am in the process of cleaning up my Testarossa and I am looking at a thin coating of undercoating on the front and rear wheelwells, any idea on the least invasive process for removing it from the inner wells? Thinners, reducers?
Thanks in advance

I have on light rubberised coatings tried thinners with good results.

You may wish to try it and do try to protect yourself from the fumes.

depending on exactly what it is, warming it with a hot air gun then scraping it might get most of it of quickly, then go to thinner or kerosene for the final clean up (kerosene is WAY safer to work around than most thinners).

The product is Dinol. It is petroleum based. It was designed to not come off in chunks like the rubber based undercoating. It stays soft and sticks well to the surface.

Gasoline makes it wash off like mud with a water hose but besides the expense there is also a minor safety issue. Kerosene is a good suggestion.

I am in Canada and haven't heard of Dinol, but I will look for an equivalent chemical.
I will definately have to throw heavy plastic tarps down and throw them out later, I have porcelain tile work in my garage.

If that is the case, the hot air gun and scraper should be magic for getting the heavy stuff off I'd think??? I've done this on other cars but never tried on the 308.

I am trying to eliminate any damage to OEM parts, the louvers covering the radiators in the wheel tubs are fiberglass and 1988 vintage, could be easily gouged if not careful and the concentrated heat might be an issue with these parts.

If you want to repair it anywhere Permatex #80072 aerosol undercoating looks very much the same.

Its never really very heavy but on a flat smooth surface that would get much of it off. Liquid solvents and a brush work pretty well on pieces that cannot be removed and soaked.



You might get in touch with Paul Newman and ask what he has done on his resto projects if any of them were late enough to have Dinol on them. They didn't start using it until early-mid eighties.

I think the correct name is "Dinitrol".

Its still made and available

White spirit gets it off after a ten minute soak!

The company is called Dinitrol. The product is Dinol.

The penetrant carried part # 900005204
The sealant was 900005205


It was VERY expensive even back in the 80's. The Permatex product is very inexpensive.
