I use a Dewalt 849 polisher with Zephyr wheels and matching compound, mostly I use the white finishing wheel / compound. Its a little work but I think it comes out pretty good. I started painting the insides of the front wheels with Flexi Peel to keep the brake dust and crap from embedding into them. I pressure wash as much as will come off then a little paint remover to get the rest off, pretty much good to go. I forget whom mentioned it but a soft rag and some flour cleans them right up, learned that trick a long time ago. They get cleaned / polished and rotated front to rear spring and fall. The truck looks really lame when I throw the 16's back on while I am polishing them. Some other good stuff I found is Gords cleaning cleaning compound. It seems to be a paint thinner based stuff with some polish compound in it. Scrub it on and let dry then wipe off, the thinner gets into the metal slightly and repels water at least for a few weeks, then re apply it. Zephyr also makes the same stuff.
