There are a number of aluminum polishes out there. I use Mothers Mag Polish. Works well. The trick for me is using the polishing wheels that you can put in your drill. I just bought some diffent shapes from Lowes. I suppose the Power Balls work well, but are costly. Someone told me to mix it with cornmeal. Never tried it.
