why not look at powder coating them instead of painting them?
probably work out cheaper and youll get just as good a finish...

My mate had his WRX wheels powder coated in white and it only cost him $200-250. ALL UP.

Check your local powder coater for specifics, might be different. But my mate also had his rocker covers done on his s-13 and only cost him $40 so should give you a rough ball park anyways.

I was considering powder coating my 04 GT 17"s, but I wasn't sure which colour (to go on a Metallic Blue 2002 RX) - and then one of my friends suggested polishing them but i thought that would take ages and probably not look as good as a good powdercoat. opinions?

If anyone has some photos of the difference between matte and satin finish powdercoated wheels would you share? I think  i know what the satin finish would look like but not sure on what the matte finish would come up like.
