A process of coating a heat-conductive strip article, e.g. aluminum or aluminum alloy strip (14) used in the automotive industry, with a solid waxlike coating material, preferably a wax-type lubricant. The process involves heating a solid wax-like coating material that melts in a temperature range of about 30 to 100 ~C to form a melt having a viscosity in a range of about 50 centipoise or less and flowing the melt onto a moving surface of the strip article through an elongated slot (15) in a movable coating head having an extended surface adjacent to the slot to form a coating layer on the article. The coating head is pushed towards the surface of the strip article as the melt is flowed as a coating onto the surface from the slot (15) to reduce a coating thickness by pressing the extended surface of the coating head onto the coating as the coating is formed. The process allows a coating of a waxlike material to be formed to a desired thickness and yet allows the wax-like material to solidify shortly after application to the strip article (14) so that the strip can be coiled without providing a cooling run of undue length or special cooling devices.
