Ok fellas here's the deal, I got some old Ansen Sprints. They are kind of rough and I am thinking about using Dow #7 on them. But I just read this on some product info. Application Notes: Castings containing bearings, studs, and inserts of brass, bronze, steel and cadmium-plated steel may be treated using this process. Note that aluminum inserts will be rapidly attacked by the Hydrofluoric acid present in the Type II activator. Use alkaline cleaners containing less than 2% caustic for ZK60A, ZK60B and some Magnesium Lithium alloys, as dimensional losses due to etching may occur. So my question is this and hopefully someone who actually knows as in has done it before knows. Can it be used on aluminum wheels and what results can be expected. I really don't want to go through the process of re-polishing the wheels that I have but I don't want to trash them either. Answers, conjecture or just pure BS welcome. Obviously answers would be better.
