"dirt" embedded in aluminum
i remember reading a thread about little specs of dirt or contamination in aluminum that ends up being smeared into the good aluminum, but i can't find it now. well, now i've got some of that metal and i'm looking for the trick. it's a shame because the metal is in pretty decent shape (shines real fast with a sprial sewn wheel and tripoly), but these little dots of crud are making it tedious. the metal is pretty flat, so should i use a 400 grit flap wheel? ...i'd have to get one or else i'd have already tried that.
