To finish up your frame, you won't need a whole lot more.
A decent drill
2 4" sisal wheels
1 4" spiral wheel
1 4" loose cotton wheel
Small bar emery (black) compound
Small bar tripoli (brown) compound
Small bar white (rouge) compound
Read the online buffing manual to get an understanding of proper technique and then have at it.
Sisal/Black should be your 1st step. This will remove the fine scratches and begin to bring a good lustre to the metal. It'll also be the most time consuming part of the polishing. Most of the polishing will occur with this combo. I sugest you move in a "cut" (against the rotation of the wheel) direction only at this point.
brown/spiral should be your next step. Start with a cut direction, go over the entire surface and then repeat in a color direction. (Some people skip brown all together and move right to white. I've begun spending a lot more time with the sisal wheel and skipping right to white as well.. Seems to work very well.)
finish up with white/loose in the color direction only and you should be good to go. Be careful with the loose wheel around edges and tight spots. Sometimes these wheels tend to grab and may cause you to scuff your part inadvertantly when the mandrel hits the part you're polishing
Good luck with it!
