A portable cart is provided for spraying viscous coating material. The cart holds a resin container and an activator container, each of which is separately heated by conduction. Material transfer lines run from the containers to a spray gun, and the lines are heated. A gas tank and pressure regulator provide compressed gas to the spray gun for spraying the coating material. The spray gun is a positive displacement gun. A direct current, double stack, low-ramp motor drives two material transfer pumps to force the resin and activator through the lines to the spray gun. The two pumps are each driven through a separate helicoidal gear box. A single 110 volt AC input provides the power for the entire cart.
