Sandblast Media Glass Bead Abrasive, 170-325 Grit Extra Fine, 50 Lb Bag, American Hawk Industrial, Mfr#: 403

There can be no doubt that Glass Beads are the world’s most popular air blasting media for cleaning and conditioning surfaces. The unique characteristic of glass sphere blasting means that surfaces are cleaned, deburred, decorated, and "cold worked," without etching or removal of basic surface material and without imparting ferrous or other undesirable residues. Consumption or breakage of beads averages only about 3% per cycle. Glass beads are environmentally safe and cause no toxic or erosive hazards.
