My home paint job sucks. how do i do this. in Body Kits & Paint Posted October 18, 2007 This is what I just learned at my age. I have always cleaned everything that I was going to paint with lacquer thinner and most time had lifting, wrinkles, etc no matter how I prepped the item. At this late date, I have just learned that doing this is a great thing to do for cleaning; but, bleieve it or not, lacquer thinner leaves it's own residue. AFTER cleaning with laquer thinner, you MUST use what most paint shops call "prepaint" (many different brands) and wipe everything down with it. It is a solution that cleans off the lacquer thinner residue and anything else. You would not believe the difference. An idiot can get good jobs using this stuff and it is cheap.
