[quote=Rebel I have some Battleship gray in my cab and on the doors that is killing me trying to get it off. Its something that was sprayed over the original and just gums up any thing I try to take it off with. [/quote]

I ran into a similar situation and found that using a chemical stripper and a razor blade worked great removing the outer layer of 'gummy' paint leaving the original paint or even down to primer still to grind off, which was fine as they didn't gum up my paper. I used 36 grit on my angle grinder to remove most of the original paint and then dropped to 80 grit from the primer down to metal.

good luck with the project

Give me ambiguity
or give me something else
