You'll need a couple of cotton buffing wheels and a buffer capable of running at about 3500rpm. (A drill won't buff them, you need higher rpms than a drill delivers) I used stainless steel buffing compound (the white stick), then finished with the redbrown stick (forget what it was called). Don't use different compounds without changing the buffing wheel. Use the edge of the buffing wheel - you'll get the hang of it quickly.
You'll leave a ton of black compound buildups all over the wheels, use regular kitchen (baking) flower to get off all those buildups. Just put the flower on the wheel and wipe with a clean soft rag. They will shine like chrome. The bad news is that you'll be touching them up about 2 times a month with a quick buff. Be careful to keep the surface flat or the dips will show.
Make them shine like chrome and you'll not believe the complements you'll get.
An angle grinder with a wool wheel works great for the polishing stage.
BTW, 400 grit sand paper will leave your wheels scored as hell. To properly polish aluminum/metal you NEED to wet sand up to 1500grit minimum, 2000 for optimal shine. Also,dont make large jumps in grit.

This will leave you with an almost mirror perfect finish
