Abstract
In an open-atmosphere powdered flame spray gun and method of spray application, a plurality of passageways extending through the gun body delivers a powderized thermoplastic, combustion air, and a fuel into an open mixing and combustion chamber defined by a hood about the body. The resultant mixture ignites melting the plastic, which is then expelled from the chamber by a source of propelling air so as to provide a plastic coating about a desired object.
