OK, I have painted and polished all four wheels, but I need to keep them that way. What do you guys recommend? Clear coat (will it stick to the polished part?), wax or what?

The painted-polished one is the one on the left.

Vaseline is recommended.

Anodizing is recommended. Vasoline is recommended in the factory manual for "anodized" wheels as the anodizing process leaves the surface porous.

I'm a firm believer in anodizing as the very best method. That said, if they're not anodized you may want to try a clear coat. Either clear powder or VHT makes a High-Gloss Clear that needs to be treated (200 degrees for 1 hour) but is rumoured to be quite tough after that.

Fuchs is the correct singular (and plural), as it is a name.

Fixed. Thanks Andy. You just can't trust us newbies.
