Rick,
I've got my wheels painted & polished & by Casoli. Mags or Ali wheels can be polished. Both will oxidise eventually. See these pics for more details
Click Here £135 per wheel at Casoli :O Look great for at least a year. Need lots of autosol to keep nice. Still oxidise and need redoing after that. I'm thiking of replacing my polished/painted ali wheels now with Mags.
