Blue Magic is a chemical cleaner like Mother's and works fine for any non-anodized aluminum. For chrome you need something with more bite. Quick-Glo is a paste with pumice and wax. The pumice degrades as you use it so gets smoother. It can take really hazy chrome and make it shine and will take off surface rust, but of course it can't replace chrome that has rusted away. Yes it works on whitewall tires too! I used it on my 1954 VW bus whitewalls!

I got this Paramount as a very hazy frame with no decals. Spent a couple hours cleaning it with Quick-Glo, added decals and lug lining, and Voila!
