if thay are in a bad situation. I would reccomend Poorboy's SPray & Rinse Full Strength & followed by a metal polish. Also the Mother's BUFF BALL with it.
Meguiars Hot Rims, Eagle One A2Z. I prefer poorboy's S&R so far its the toughest on rims. but if you want something local get the A2z heard good things bout it. :-D
