I recently bought a small compressor with tools for my father’s car workshop. I also got a shotblasting gun that that uses the venturi effect to draw grit from a bag and blasts it out with the aid of the compressed air.
While effective at removing rust and old paint, it is incredibly messy. I resorted to wearing a motorcycle helmet, balaclava, overalls, gloves and boot and would still find it the grit in my ears and inside my clothes after a blasting session. Also it went all over the workshop. With blasting cabinets costing more than the compressor did, I decided to build my own.
