I bought a random orbital from Griots and it's been the best car care product I've ever spent money on. Much better and faster than doing the polishing and waxing by hand.
I second that. Along with Meguiar's Swirl-X and Meguiar's Polish the Griot's orbital does a great job getting rid of the swirl marks. The orbital is also great for applying wax.
