Kevin,
Now that I've got my booth finally set up I'm considering not trying to drag my top heavy compressor to my temporary booth and spraying with some industrial compressed "Breathing Quality" air. I figure an advantage to this would be an absolutely clean air supply; I wouldn't have to worry about oils or other contaminants.
I was wondering if there would be any down side to doing this other than a limited air supply and the moderate cost (about $50.00 for 3 large bottles)
Thanks in advance!
