If you are going to polish a limited number of small pieces and don't want to spend $300 on buffer, you can go this route:
For a nice satin finsih just buff with Mothers aluminum polish on a rag.
For a mirror shine, buy a 6" stiched cotton wheel for your drill motor and a stick of tripoli or other soft metal buffing stick from Lowes etc.
Buff aggressively and that will remove the fine scratches and extruding lines in the aluminum. Finish off with Mothers either by hand or better yet with another wheel or a wool bonnet on a paint buffer.
Another vote for Mother's. I use an el-cheapo electric polisher. I use the lamb's wool first and then follow-up with another go of it with the lamb's wool pad covered by an old cotton tee shirt. Works well and is cheap.
Along with Mother's Polish, Mother's Powerball, fits right in drill and sure saves time, I just got a kit with a large and a small ball, very handy, would buy again in a heartbeat. The plastic polish worked great also.
