This stuff is the shit when it comes to polishing metal. I used it all the time on my Silver charger's chrome clad wheels (when they weren't plasti-dipped!). It got off spots that Mother's and Meguire's wouldn't touch. Here's a before and after pic of the chrome tail light bezel of my fire engine up here in NY. We had 4 different types of metal polish/cleaners sitting in our cleaning cabinet. I told the officers to try using their stuff on the other side, and then I did the driver's side using purple polish. They were amazed.
