To start with you might want to contact some local paint and body shops in your area and see what they say. Secondly, you might want to practice on a few old cars before you tackle you MB. Auto paints are VERY expensive and VERY tricky to apply.
By the same token the price for a professional paint job esp. on a MB and ESP. in your area (my wife is from Palo Alto) can cause your heart to stop. It might be worth the effort to take your car down state to LA or some other place where the competition is stiffer and the prices a bit lower.
