Looks great man, plus its a sweet car as well. For Mercedes clear coats you should try out the
Menzerna line of polishes. As gamby said they do dust a bit but work great. Megs 105 is a phenomonal compound on hard clears like the newer Benz has. Waxes and sealants you are going to have to play with them and see which ones you like better. I have used Dodo Juice's Super Natural and its amazing on black. There are
TONS of products, and this site will make you buy a bunch of them trying them out and finding what you like best.
Car looks great, now cut up your credit cards so you don't go broke now that you have been bitten by the bug. Take care
