1. A method for protectively coating a substrate, comprising:

  • introducing a flowable mask material into at least one selected communication port of a substrate to define a mask in the at least one selected communication port, the flowable mask material substantially conforming a shape of a surface of the at least one selected communication port under natural force;

    applying a mechanical force to the flowable mask material to conform the flowable mask material to the shape of the surface of the at least one selected communication port after the flowable mask material has been introduced into the at least one selected communication port, wherein the mechanical force is applied by an instrument that does not form a part of a finished device including the substrate, wherein the mask bonds to the substrate;

    applying a protective coating over the substrate and over the mask, such that the protective coating adheres to the substrate and the mask;

    cutting the protective coating at locations outside an outer perimeter of the mask, wherein cuts from the cutting the protective coating does not extend completely through the protective coating; and

    removing the mask and at least a portion of the protective coating over the mask.
