Why not use regular sand? I ask, as I live somewhat near the middle of
nowhere, and have done sandblasting outside, where the retention of the
media (filtered playground sand) isn't an issue. Aside from the silica
issue, for which I use a full painters mask (the nice kind, not just a paper
filter). I haven't found any problems yet (with the metal, but I really
haven't done a lot of it yet- should I be concerned?
thanks!
