ABSTRACT:
In a method of manufacturing, the steps of: providing a workpiece comprising a main body and a machine-readable marking on a portion of the body, depositing on the marking and the surrounding surface an overcoating of a liquid polymeric composition that is curable by exposure to ultraviolet radiation, and then irradiating the liquid overcoating with ultraviolet radiation so that the overcoating cures to a solid nontacky, light-transmitting protective coating. The workpiece, with the cured protective coating thereon, may be subjected to processing steps wherein extraneous matter may adhere to the coating, and then be cleaned leaving the cured coating intact.
