The package says #8 Glass Beads. Under a magnifying glass, there are
certainly some beads in there, and lots of fines - of course, I happen to
have grabbed a HF magniflying glass too.
I'd guess it's maybe 20% beads - sort of what I'd expect to see after lots
of blasting. Or maybe what you might expect from fresh HF glass beads :-(
Glass beads are what I've almost always used in the past, except before I
knew better than to use 100-grit silica sand (and that was open blasting).
What do you use for rust and paint ? Aluminum oxide ? Black Beauty slag ?
