Glass will make a piece of old tarnished stainless steel look nice!
Its easy to change the media in my Skat Blast cabinet so I use sand, glass, plastic(but not often)...just depends on what I'm working on BUT for the most part I use Fine Blasting sand that I get at the concrete mixing plant. Its about $4 a bag for 50lbs. It gets most everything I have a need to blast and its "sized" and flows good. However, there is room for the need of several media's.
