Fastener-coating tools, kits thereof, and related methods

A fastener-coating tool (100), comprising:

• a non-permeable body (102) that comprises a non-permeable wall (104), having a closed shape and comprising:
• an inner surface (108) that defines an internal cavity (106) in the non-permeable body (102);
• an outer surface (110) that faces away from the internal cavity (106) of the non-permeable body (102);
• and
• a terminal surface (116), having a closed shape and interconnecting the inner surface (108) and the outer surface (110) of the non-permeable wall (104);
• and
• a permeable body (112) that:
• laps over at least a portion of the outer surface (110) of the non-permeable wall (104);
• laps over all of the terminal surface (116) of the non-permeable wall (104);
• laps over at least a portion of the inner surface (108) of the non-permeable wall (104);
• spans the internal cavity (106) of the non-permeable body (102);
• and
• defines a fastener cavity (114) that extends at least partially within the internal cavity (106) of the non-permeable body (102) and that is sized and shaped to receive a portion of a fastener assembly (50) to be coated, and wherein the fastener cavity (114) has an open end (118), proximate to the terminal surface (116) of the non-permeable wall (104), and a closed end (119) within the internal cavity (106) of the non-permeable body (102) and opposite the open end (118).
