A process for heat treating a coating applied to an automobile body with an apparatus having radiant heating means including a plurality of infrared heating lamps for generating radiant heat in a predetermined path and convection heating means for generating a flow of heated air in a predetermined path, said lamps divided into a plurality of separately controllable zones where an infrared intensity of lamps in one zone may be adjusted to be different from an intensity of lamps in a different zone, the process comprising the steps of: (a) positioning an automobile body having an applied fresh coating in the path of said radiant heat; (b) partially heat treating said coating by radiantly heating said coating with said radiant heat for a time sufficient for said coating to set; (c) during said radiant heating, controlling an intensity of lamps within a zone to have an intensity selected in response to predetermined characteristics of said body exposed to said zone, and said radiant heating taking place in an absence of a flow of said heated air which would disturb said coating during said radiant heating; (d) positioning said body within the path of said heated air; and (e) subsequent to said radiant heating, containing heat treating said coating by convection heating said coating with said flow of heated air for a time sufficient to cure said coating.
