[Shop-talk] Garnet blast media?

[David C.]

Garnet would probably be a lot more aggressive than glass beads and good 
for rusty stuff.  It's commonly used as the "sand" in sandpaper.  I 
wouldn't use it on aluminum or anything soft, though.

I leave glass beads in my blasting cabinet, and save the rougher media 
for the pot feeder to be  used outside on larger and/or more rusty stuff.
