Riverhorse, that acid stuff that they will drop your parts into I hear is good to do right after the company gets new fresh acid back in the tanks. Some people told me this and I read it in a few books. I think someone on here might have told me that as well, I don't remember. If the plating is comming off then try sand blasting the parts maybe. I am going to be sand blasting my grill, bumpers and a few other parts where all the chrome is peeling off and just powder coat them chrome instead of plating so I don't have to worry about chips and cracking or peeling.
