Champion aluminum radiator polishing

Make sure the metal is clean before trying to polish. Try a terry cloth rag instead of the microfiber. MF cloths, in my experience, will put swirls into things far faster than terry or other soft cotton.

I am wondering if it was dirty. I didn't even think about that. :banghead: I have a powerball, maybe I will give that a try.

Any ideas for the scratches?
