Any tips out there for removing scratches from glass glitter wraps? I read the thread about Oyster and Pearl wraps, but I'm curious if anyone has tried any of these methods on old glass glitters. It seems to me that they are a bit thinner on the clear coat than today's glass glitters which makes me quite nervous about the idea of wet sanding. I was considering the Novus product that is mentioned frequently on here. Any tips would be greatly appreciated. My trusty RB's need a little touch up!
