hey, how exactly do you polish aluminum? i'm going to paint my intake manifold and instead of taping off the fins, i think it would just be easier to polish the fins? that and my aluminum intake elbow needs polished. thanks guys.

I use steel wool to clean the aluminum, then sand them down, polish them with a dremel and polishing compound, and then go over them with another polish (been using Never Dull). Seems to work alright but takes time.
