I redid the wheels on my 300ZX. I just went to the local paint store and picked a color I liked, bought a pint and brought that to my local body shop to have them sprayed. I also had them use a clear coat I bought from
Eastwood Company: Auto Tools, Body Repair, Classic Car Restoration, House of Kolor Paint, Powder Coating that is made for wheels spacifically. They sell the clear in both spray cans and quarts. It is a special clear made just for wheels. They turned out great, but I would definately use this special clear coat. Its much more durable.
