Zaino brothers came out with a product recently which is supposed to be at the top of the market for taking care of swirls and other paint problems. It is called Zaino Z-PC, goto
www.zainostore.com and i beleive its $12.95 per 8 oz bottle. Havent tried out myself since I dont have paint swirls, but from what I am hearing this might be what you really want. I also suggest using most of their products in regards to maintaining your paint.
