John, look at powdercoating. Fantastic process, you can simulate just about any type of finish. Chrome, silver, gold, matte black. Basically whatever you want. Also powder coating is seriously scratch, chip and rust resistant.
A bit pricey, but after I looked at the price (new) of the wheels you're trying to refinish, I realized "a bit pricey" is relative. I think you'll be pleased with the results.
