ABSTRACT:
A multipart seal is provided for electrically isolating from an electrolyte medium a projection secured at a projection base with a body surface, the projection and body surface having different electrochemical activities. A first seal part is a hollow cap sized and shaped to receive and cover the projection and to conform with the projection base. A second seal part is a cured, pliable sealant disposed on a cap wall about a cap opening and cap rim portion, and bonded with and covering the projection base and the body surface surrounding and immediately adjacent to the projection base. Both the first and second seal parts substantially will not react with or allow passage there through of the electrolyte medium. In an electrolytic method to coat the body surface, the projection is electrically isolated with the multipart seal prior to application of the electrolytic coating.
