I was wondeing what you guys use for blasting media in a cabinet. I've considered aluminum oxide and the crushed glass. The price on the glass makes it tempting but I'm leaning toward the aluminum oxide. I've got a cabinet that I made and it's pretty big (48"L x 32"W) and it's gonna take a lot of media to work decent. I've been using sand and it's okay but I want to try something different in it.
