I have a chopper gun, I'am having trouble keeping my resin warm (5 gal pals.) I work out of a garage in upstate N.Y. this is a project that I want to turn into a full time job. My heat in the garage is not on all the time because I work on another job during the day. When I spray the resin it doesn't fan out of the spray tip. It comes out a straight stream. I was told this was because the pump can't pump cold material. How can I keep my resin warm without burning down my garage?
