The wheels were chrome. He charged me $60.00 per wheel. As for the exact process he used I am not sure. I trusted the guys knowledge as he has a whole shop full of custom motorcycles and cars he is working on. Real high end, show quality stuff. You can check out his web site at
www.powdercoatingit.com/ . Located in Plainville, Ct. He was really nice to work with and the turn around time was one week. I will let you know how they hold up but I am pretty confident in the workmanship.
