Abstract
A method is provided of applying a coating material to a concave surface of an article that has a rim around the concave surface, and a cavity between the concave surface and the rim. The method includes discharging coating material in a liquid form into the cavity, extracting a first amount of the discharged liquid coating material from the cavity, thereby leaving a residual amount of the liquid coating on the concave surface within the cavity, and maintaining the article in conditions appropriate to allow the residual amount of liquid coating material to cure on the concave surface.

An application system for use in coating a generally concave surface of an article with a coating material, the article further having a rim around the concave surface, and a cavity that is defined between the concave surface and the rim, the application system comprising:
- a reservoir within which to contain the coating material in a liquid form,
- one or more nozzles that each have a tip end, and at least one lumen that extends through the nozzle to a respective opening at the tip end, and
- a coating material transport subsystem that is in communication with the reservoir and the nozzles, the coating material transport subsystem being configured to deliver liquid coating material to at least some of the lumens for discharge via the respective openings, and to draw liquid coating material into at least some of the nozzles from externally of the respective nozzle.
