sandblast the whole car???

Anytime you are going to repaint a car you should take it down to bare metal. Most good blasting shops use crushed walnut shells(won't warp panels) I have personally found that you can sandblast any jamb panel, engine compartment, and trunk with any plain old sandblaster and not warp the panel. But don't try it on any outer exterior panel it will warp it. I think if a guy has the room to do his own panel stripping, weather its chemical or sanding, you could save yourself $1800 large that you could put toward something else on the car
