Rolite
For metal polishing:
Rolite metal polish is great. It's been re-packaged by several popular motorcycle brands as it's a fantastic product.
So, bare aluminum, rolite Metal polish, (Not the Pre-polish it's much too coarse) then if you want the "Oshkosh" finish use the rolite AP-300.
For polishers, make absolutely sure you don't mistake an angle grinder for a polisher. They turn WAY too fast. The cheap polishers don't have much power but that may be a bonus if you're not used to using one.
Use the polisher on an angle, not flat and make sure the spinning edge flows off the trailing edges, if not you will bend something.
Put the product on the pad or on the surface you are polishing and start very slowly to work it into the pad and on the surface otherwise you'll end up with a line of polish adorning your coveralls. Don't use too much product at a time as you'll end up polishing polish if you know what I mean.
A LITTLE water from spray bottle helps keep the pad from gripping too when the carrier starts to dry.
Google rolite polish and you'll find a great article or two about polishing, before and after pics etc.
Be extremely careful around edges, antennas, fairings etc. I'd reccommend doing them by hand.Have fun!
