Several months back. I bought a Harbor Freight touch up spray gun.....8-10 oz capacity feed cup. It was less than 15 bucks. It works fine as frog hair @ 40 PSI but that is really not my point here.
I also use Argon/CO2 mix for MIG welding. That got my mind to wandering.....don't take much these days.

.
Has anybody here ever tried using this compressed gas in lieu of a compressor for painting? I don't know the CFM capacity of the MIG regulator....which would be a game stopper if too low.
I figured this would be the spot to ask a dumb question before I start fooling around with some lash up to attach the regulator to the the gun.
Hay, it is either this or speculation if SammyG and Rweb are/were one and the same........
