I use 3M™ Perfect-It™ 3000 Swirl Mark Remover #6064 after wetsanding (1500 followed by 2000 grit) for filling in paint chips and such. It is supposed to be good for dark colored cars (mine's black). I'm pleased with the results and this is only using a cyclo polisher. I think they're more intended to be used with rotaries by the "professional" user.
Also, my buddy works at a high-end paint shop, and they exclusively use the 3M stuff. For what its worth!
