For most things I use glass beads, but for tough rust on heavy parts I use crushed glass. I've had really good luck with the glass beads on nuts/bolts and real sensitive parts like thin sheet metal, my motto is if it fits in the blaster it gets blasted, I even made an extension for mine to accept 6 foot long pieces, it fits right on the door. I don't see how you can do a restoration without a blast cabinet.
