Polishing zinc coated billet aluminum ????
Polished my a-- off on some aluminum wheel centers only to realize they are zinc coated and won't polish until the zinc is removed. I want to put a mirror polish on them to match the wheel rims. What is the best way to cut the zinc coat to get to the aluminum ??? Anyone done this ?? Thanks for the help. I hate to just grind them down and have to polish out deep swirls.

Re: Polishing zinc coated billet aluminum ????
If done right the zinc coating is a bear to deal with. It sure does protect the part. Good luck.
