Restoration of factory GM aluminum wheels
I have a set of factory GM 16\" \'GTA\' wheels that have spots in the aluminum. They almost look like big rain spots. The spots are a faint white color. I have removed the clear coat and it\'s still there. Tried some metal polish and that did not help either. So I was looking on the Caswell site but am unsure of what exactly I need. From what I\'ve been reading I need both brown and black compound. New to buffing so I really don\'t know much about this.
