Aluminum Car wheel polish, hmm.. I’d say sub optimal. Guessing what’s in it it’s probably a cleaner, an abrasive, and a wax. Aluminum and magnesium are both a good bit softer than silver, and car wheels don’t get polished till they have big gouges in them. Also their system of oxidation is different from silver. The abrasive may either do nothing or take off a lot of metal because the granules are big. plus you don’t need the wax gumming stuff up.
