Abstract: A unitary arrangement for quickly and effectively coating ski runners and similar planar surfaces with a heat-plasticizable, wax-type coating substance is described. An elongated container for the plasticizable substance is resiliently and telescopically arranged within an upwardly projecting hollow flange portion of a coating-application member, and a burner nozzle is removably secured to the container and is arranged to direct a flame either against the container wall or the wall of the application member, both of which are formed from a heat-conductive material such as brass. A downward manual pressure on the container serves to open a normally closed valve between the container and the member to complete a communication path between the interior of the container and a coating slot on the bottom of the application member, while the simultaneous activation of the nozzle will plasticize the coating composition in the container via heat conduction.
