A compressed air gun and a method of spraying plural component coating materials so as to provide an article with a substantially uniform, continuous thin film about one to two mils thick. The gun includes means for rotating about its axis a chamber in which the components of the coating material are mixed and ejected from a position where the components are introduced to the chamber to a position where the introduction of such components is terminated, means for forming the material ejected from the apparatus into a spray of the type necessary to provide the substantially uniform, continuous thin film, and means for purging and atomizing the residue of the material from the mixing chamber by a flow of compressed air therethrough immediately following the termination of the flow of components into the chamber. |
