Neither did I, but fortunately the clerk at our local Grainger did. After I
described the piece I was hoping to blast, and it's function she helped me
choose the correct grit.
Apparently some glass beads, at the correct pressure can be as abrasive as sand.
I use a fairly mild grit, that impares a high gloss on aluminum without moving
much metal.
If someone out there is interested, I can forward the make and part number
tomorrow.
