Abstract
There is disclosed an assembly for selectively coating a hollow, cylindrical first substrate defining a first open end region having an outer surface and an inner surface and a second open end region, the assembly including a first plug member fabricated from a nonwetting material, wherein the plug member has a bottom surface defining a pallet coupling feature and a top surface defining a cavity region encompassed by a circumferentially extending rigid side wall having an outer surface and an inner surface, wherein the first end region of the substrate is disposed in the cavity region where the inner surface of the side wall grips the outer surface of the first end region of the substrate to couple the first plug member to the first end region, whereby the plug member minimizes coating of the outer surface and the inner surface of the first end region of the substrate by a coating solution.
