An inexpensive gel coat gun for spraying small to medium size molds. Avoids the high cost of catalyst injector systems and at the same time avoids the pitfalls of a regular spray gun. The resin and catalyst are mixed in the disposable paper cups, the lid and nozzle assembly are pressed on, and the cup is then placed on the gun. With the paper cup in a level position, depress the trigger and the air stream picks up the gel coat and provides a uniform, high velocity spray pattern. To clean up, merely remove the cup form the gun, and just clean the lid and nozzle. Cup capacity is one quart. We ship the gun with a 3/16" ID nozzle, but others are available.Pressure required –60 - 100 psi Air consumption – 5.8 CFM at 80 psi Compressor required – 5 HP Air connection - 1/4" TPR Dry weight – 2.0 lbs
