Wow! Impressive. I'd start with a 120 grit flap wheel to get the rest of the easy-to-reach stuff and a wire wheel on a drill for the nooks and crannies. What's left of it is probly real brittle and about ready to fall off. You can get the wheels that are on that Eastwood thing Keith sent a pic of, at HF, Sears or just about any autoparts.
