Not really, gave the wheels a good scrub and clean when i took them off, then used emery cloth to take most of the heavy marks off followed by wet and dry sanding down, then just painted them they way you would any other thing. Not that hard to do. The paint I used was Simoniz silver wheel paint, the lacquer was just some Halfords own brand i had lying round. Actually the only part which is a pain in the arse is the masking up of the tyre........ :tsktsk:
