I just got one of the el cheapo harbor freight blasting cabs. Im trying to keep the mess to a minimum. It says to only use glass bead. Why no sand, alum oxide, etc. I hear glass bead is good but it breaks down fast. Any body have any experience with different types of media and why I should or shouldnt use it. 90% of what I blast will be to powder coat. Thanks for any tips. Mike
