Have worked every afternoon this week for at least three hours wet sanding the Champion. Did this last spring and it looked good when I finished, but it really began chalking over the summer on the top cap where its black with silver flake. I'm not sure if I didn't go deep enough or if I just need to do a better job at keeping it waxed. Thought I was. I put the first coat of Pro Tec sealant on yesterday and will finish with the second coat this afternoon. Should I put a coat of wax...say Meguiar's with carnauba on top of the Pro tec? I definitely don't want to have to do this again next year.
