My wheels are starting to look pretty ragged. It seems as though the clear coat or what ever they put on is starting to flake off, so in some parts its perfectly shiny in others its flaky and dull, so I'm trying to figure how to correct this problem. I don't really want to have to take the tires off though. Am I able to just sand it down and use some aircraft remover etc then polish it like mad or do I have to apply some sort of clear coat? If I have to apply any clear, am I able to do this without taking the tires off? I wouldn't mind taking them off but this seems like it will take some time and I only have one set of wheels...
