A process is disclosed for the production of a sun heat energy absorbing coating on a metallic substrate. The metallic substrate is pretreated for subsequent coating with a film of powder varnish and thereafter a coating based on a solid synthetic resin is deposited electrostatically or in a whirl sintering procedure. The coating consists of an inner brightening layer containing a metallic powder and an outer colored second layer absorbing the sun energy.
