I bought some II Crave wheels, these http://www.2cravealloys.com/wheel_4c-1.htm, for my 07 Tahoe and was going to have them powdercoated matte black. When I took them in they said they could not do it because the middle piece that is plastic will melt (which I could paint later) and also the little rivets around the inner edge are actually plastic and will melt and pop out leaving little holes. It looks like my options are to go through with it and have little holes all around the inner rim or return the rims with some hefty shipping and restocking fees. Any thoughts or ideas? Are most of these rivets plastic or only on cheaper wheels?
