I do NOT recommend Wheels America. I sent my wheels to them not one, not two, but THREE times to be chromed, and each time they came back polished. Not only where they polished, but there were tons of imperfections in the finish. Eventually they blamed the delivery driver for all 3 "polishing" instances, saying that repeated calls, faxes and emails doesn't affect the order, and ultimately said that I was too picky and left me with half-assed polished wheels.
When I originally inquired about repair, everyone insisted California Chrome was the best out there, but you have to pay to ship your wheels both ways. I think they run about $150/wheel?
