Can anyone recommend a decent suction feed blast gun. I just got one of these cheap ebay blast cabinets (SBC220) which I cant fault for value but the supplied blast gun is about as much good as a chocolate fireguard. I have only got a 14cfm compressor so I believe I am correct is saying I need to stick to a 3mm nozzle. At the moment I am considering converting it so I can use my pressure pot. Any Suggestions?
