I have a few guns that I duracoated and the paint is coming off. I've got some Norrells Molly to redo it. I don't have the money or room to buy a high dollar blasting cabinet. My quistion is can I get one one of those outside blasting guns and use sand to blast the duracoat off? If so what would be the best sand to use that can be found easily? I know it's best to use 120 alum ox at 40lbs pressure, but it's just not feasible for a few guns and no cabinet.
