Spray equipment is used to apply fiberglass reinforced plastics onto mold surfaces. Such spray equipment includes a nozzle designed to allow flow of resin to a point of application as well as an outlet dispenser of small cut pieces of glass which aims the glass into the resin flow so that the resin and glass mix beyond the nozzle exit. A second nozzle is positioned below the resin nozzle and is angled slightly upwardly at the resin stream in the form of an air knife. The air knife causes the resin stream to uniformly spread permitting the chopped glass to fall within the resin stream and uniformly mixed therewithin for application to a mold surface.
