I have some motorcycle parts that are chromed billet aluminum (headlight, fender struts, etc.) that I want to powder coat. I have purchased the entry level hot coat gun and the powder coating handbook offered by Eastwood. I don’t see much info about coating chrome parts. Do these parts need to be bead blasted prior to powder coating? I have tried bead blasting some old chrome exhaust pipes and the glass bead has very little effect on the the chrome. Do I need to do this or can I powder coat over the cleaned chrome part?
