Hi, I'm refinishing a set of Rotas because the clear started chipping off the lip (drove them in winter, but hey they're Rotas thats what they're for) I wet sanded them all the way up to 2000 grit, and they don't quite have a mirror shine, but I like the raw look. When I purchased the clear coat at the paint store I told him it was for aluminum, and he said this stuff will work, but he said a powder coat clear is the "right" way to do it. Would the clear adhere to the wheels? They're pretty smooth, but I see people sanding up to 1500 before they paint. Should I just scuff them and paint them instead?
