Abstract
A process for heat treating a coating applied to an automobile body is disclosed. The process is carried out with apparatus which includes radiant heating elements for generating radiant heat in a predetermined path and convection heating elements for generating the flow of heated air. The method comprises the steps of positioning a freshly coated automobile body within the apparatus and heating the body with the radiant heat for a time sufficient to set the coating on Class A surfaces of the body. After the Class A surfaces are set, heated air is flowed around the body to heat the body and cure the coating on the Class A surfaces and the non-Class A surfaces.
