The only painted wheels I have waxed were the ones on my boat trailer.
I just used whatever OTC cleaner/wax I was using on the boat at the time.
Sometimes it was Mothers, sometimes it was Meguiar's.
Chances are I would use whatever products I was using on the paint of my vehicle. The only negative I can think of in that is the heat that brakes might generate could have an adverse effect on the wax. I've heard that for years, but I can't say I have ever experienced it.
Actually, I guess several of my custom wheels have been painted. Clearcoat, but it is still paint. They always got whatever the rest of the vehicle got.
