    Elaine, What are you trying to do? Are you removing material or just
    texturing? What material are you going to blast? Sandblasting removes
    material, although not much from metals, and leaves a dull matte
    finish. Bead blasting removes no discernable metal and leaves a
    matte to sparkling finish depending on the glass bead size, volume
    of media flow and air pressure. I do a lot of both. If you want to
    send me a small piece of what you hope to blast I can do a 220 grit
    silicon carbide sand blast and a 70 - 120 grit bead blast  to show
    you the difference. Email my off list and I'll give you my address.
