I have an old Kerker system on my 1984 ZX550A1 GPZ and I believe it was originally finished with a 'ceramacoat' system (or something like that). At this point, its coated with nothing but surface rust in a bad way. What would you recommend for refinishing - send it off to a powdercoating shop, have them strip it and powdercoat? Maybe I can just sand down the rust and paint with a high temperature paint.
