Yea, compressor is next on the list - probably going to Sears this weekend. One o' these:

Pretty good price. I thought about a cabinet, but the stuff I want to do requires a portable unit versus a cabinet (large panels, etc.)
There's a local place that has about a bazillion kinds of media so I'll go in there next week and talk with them about the "proper" kind for various types of work. I fiture glass beads of 200-ish grit should work pretty well for most P-car parts though.
First goal for my own car is to get everything on it working exactly as it should, then disassemble it completely - right down to bare metal. God knows what's on the body after 34 years. Basically if it didn't come from the factory, I don't want it on there. Engine compartment & floorboards keep a healthy coating of POR-15 and the chassis/tub goes in for paint other than that. Then the real fun begins.
