The fountain applicator handle includes an elongated hollow reservoir with sliding displacement piston disposed therein. A valve body is attached thereto and adapted for attachment to a coating supply, with the valve body allowing the communication of the coating into the reservoir while preventing the outflow of the coating to the applicator, and controllably communicating the coating from the reservoir to the applicator.
