Preparing to soda blast the engine and gearbox cases, etc. I finally got around to repairing my big compressor -- a deVilbiss 5hp rig that's supposed to push 8 cfm at 90 psi -- 20 gallon tank (sticky check valve). Runs great now and should be plenty powerful.
I see siphon guns online for as little as $12 and as much as $60. What do you use for soda, with what kind of nozzle?
