Hey!
I can't speak for your depth of swirling, but using Ultima is a snap. I started with a PC, a couple of orange EDGE 2000 pads, and the Ultima system and ti worked well on a Lexus LS430. For six month results check out the link.

Make sure you wash and clay the finish first.
My main concern is that MB uses really hard paint and that you won't be able to knock out the swirls with Ultima PPP. You may want to consider Menzerna SIP and or 106ff. If you are using a PC it will require a good many slow passes before you break the polishes down. Use a halogen light to aid you in your work.
Anyone else?
