Can't find anything on this subject in the search. I want to paint my truck with a single-stage enamel industrial paint. It has the regular factory paint right now. Can a person put the enamel over the factory paint? I think a friend of ours scuffed his and painted recently and when he pressure washed it, the new paint came right off. Any tips? I'd hate for that to happen. Thanks. Can't wait to ditch the 2-tone brown!
