That body looks fantastic! I have to assume that the graphics are actually decals, (checkerboard and hood pattern) right? The lines look very clean...I would really love to hear all of the steps that you took in order to come to that end.
I am still waiting for my MB, so I have been practicing on a sheet of Lexan, but I have run into several problems. Finally, I have decided to use a silver sharpie (permanent marker) to make the precise lines and dots, and painter's masking tape to divide the color sections, before spraying the metallic silver overlay and navy blue stripe. Any mistakes will (hopefully) be hidden by the sticker/decals.
I can't wait to get started. My MB is going to be painted like an old bomber airplane, with stars, stripes, 'sheet metal' and rivets. I am even going to mount a small propeller at the front of the hood that will spin as the car drives forward. It sound a little goofy and unrealistic, but like I said, it will be small and should not get too damaged.
Please, feel free to give any advice that might help me keep from screwing up.
