I use Silica Sand, which is Labeled NOT FOR SANDBLASTING on it, just to cover their responsibility. I do it on a big plastic tarp, and you can scoop it up again and sift to re-use more. Yes, sand gets into any little place, I found some in places I even had taped tight as I thought. I also have home-made unit, same sand in it. You can get the black bueaty stuff some places. Tractor supply has some in pails. TSC. You need to get a catalog from TP tools in Ohio. They have tons of blast stuff, costs quite a bit, but catalog explains many things and has good pictures to show what to use and why. They have all the material, but pricey. I built the kit/plans they offer with some of thier parts. I reccommend the Hardened metal tips, others are gone quickly! IN cabinets the tips and glass wear out or frost over fast, need changinb often. They offer a liner for glass, I just have safety glass and put a plexiglas inner peice on it's backside. I did use plain glass their, but plastic lets sand bounce off and lasts clearer longer. You should have a shop vac hooked up too, or you wont be able to see in a minute with all the dust in cabinet. Try www.tptools.com for catalog and on-line info is good too. Eastwood is another place, pricey, but neat odd tools. TSC again has quite a bit of accessories for blasting and air, at least by me it does. Walnut shells are more for stuff that can't be harmed, like electric motor windings and such, as the sand really rips into stuff, leaving a sort of rough metal surface. I often remove part, then use my wire wheel grinder to smooth it back down to reg looking metal surface again, it does instantly. Paint right away, starts rusting real soon, and you'll be doing again to knock off rust film if you don't.
