ANYONE EVER made a spray rig at home? I mean a spray rig that will spray 30'-40' on a barrel or good sizr tank? i used a homemade rig with a diaphram pump but the mixture i used, i belive messed up the diagphrams. lets say it had a little petroluem base to it. I NEED the flow rate pretty high the one i used had a 4.9 gpm. worked well . but it didn't make the next trip and i have a lot to spray and atv sprayers just don't cut it at all. i'm tired of playing around i need power :cowboy:
