Michael,

I am not sure about that product, but i would first try with some thinners and see how that worked on it, and then move onto some heat ( heat gun, not a propane torch)
I am assuming that this is a waxy type substance, and not the thick black undercoating type of rust proofing. What ever way you look at it, be prepared for some elbow grease and lots of time....

good luck,

Mitch

I had the black stuff all throughout the engine compartment. I was recommended to use EZ OFF oven cleaner. It worked well and smelled pretty good as well. But,no doubt, it took a lot of time and effort. A little heat from a heat gun worked on the really thick stuff.

Good luck

Bill

Trying to pciture the stuff they used. If it the gloppy and has lots of little peaks in it a needle scaler can work well. The more pliable it is the more likey the Oven-Off and/or heat gun will work.

Be careful when doing this...

Keep us posted on how it goes!

If you can get to clean metal from behind the coating, a little heat with a propane torch will soften it enough that you can peal it off with a putty knife. Do a small area at a time. Then wipe the residue of with mineral spirits.

Be aware that heat can also take the underlying paint off if that's not what you also intend.

Thats why I said a <span style="text-decoration: underline">little</span> heat. Just warm it up but not enough to soften paint or warp panels. Test in a secluded area.

Unless the paint is coming off anyway! If you don't mind getting messy, and the paint is in fact coming off then a wire brush on an angle grinder will make short work of it. And anything else it touches...
