My parents got me a small table top Harbor Freight sand blasting cabinent, 36" X 26" I belive, but when I opened it up, the glass was smashed, so my mom is exchanging it for a new 1, of the same model on tues when they get a new shipment in of them. but whail she's there, I'm going to have her pick up blasting media, but what do I want, they sell aluminum oxide, glass beads and sand. I want to just do basic rusty parts clean up ( brackets, ect... )?
