A tad off topic ... but one of my grills had two broken pins so I made a couple of replacements on the lathe out of nylon, tapped them for 10-24 and run a screw in from the bottom. Seem pretty sturdy, as sturdy as the originals anyway.
Going to throw some walnut shells in the blaster and see how it performs on painted plastic, sometimes those shells can surprise you and produce an almost virgin finish on things.
