That may have been me.

Original I purchased Wolfgang in 2007 and the plan was to use on the polished alum. bits to help prevent oxide from re-forming after polishing. Discovered it left a silky, soft and an incredibly glossy finish. It works great on Aluminum, chrome, auto paint, glass windows and lead crystal. UNFORTUNATLY, it has very short durability.
