My hotcoat gun seems to have a problem. When I shoot with the pbutton down the powder flows right past the part. I even shot powder right at the alligator clip and it still flows right on past. I can hear a buzzing sound right at the shrink wrapped joint on the gun when the button is down. The powder seems to be more interested in sticking to the gun barrel now. Guess I’m waititng till monday to call Eastwood.
