As for the media compounds the directions suggest Aluminum Oxide, Pumice, Starch, ect. The kit includes a full 6 oz. jar of aluminum oxide. It requires 10-45 lbs. of air pressure to opperate. It suggests 30-45 lbs. for metal and plastic work. You should be able to use any air brush compressor or any home compressor with a regulator. This is an older kit, but it is new and has never been used. To be honest I think it is made better then the ones they offer today. Hope this helps answer some of your questions .
