Blue Magic polish is much better than Mother's or anything else.
In the 2000's I had a sports car with very expensive HRE wheels which were non-clearcoated polished aluminum. I was living in NJ unfortunately and the rain up there is very hard water. The water spots it left after every single rain shower were horrific, almost like it was corroding the aluminum. I tried Mother's and every other store bought polish and nothing would get rid of the spots, not even a little bit. Then I came across Blue Magic at Advanced Auto and it completely wiped them off with no effort. Now I use it to restore and polish up vintage bike parts. Mirror finish after wetsanding.
