Salvage yards out here in Washington write their stock numbers on their parts with yellow paint; I want to remove these scribblings from my parts. I've tried traditional paint thinner, "Bug&Tar Remover", and even Mother's Polish with a drill and disk. Nada. I can't use abrasives, want to protect the aluminum from scratches.
What do I need? Acetone? Turpentine? TIA
