use terry cloth towels (all cotton) they won't scratch the paint at all and buff out wax very well. I know a lot of people are useing microfiber towels for waxing, but I'm not sure how well they work...never used one.
You can buy a bag of terry cloth towels from autozone and murray's for pretty cheap.
