Do any of you guys know how must dust accumulation there is with other abrasives besides sand? Are there plastic beads you can use instead of sand? I am looking to buy a cheap blaster to blast my axles before I swap them in. However I don't have an ideal place to blast them, it would have to be in a small storage shed in the backyard. I could you a grinder with a cup brush on it, just another thought I had. Thoughts, ideas?
