Abstract
A weatherstrip assembly includes a body having a carrier or core formed from a first metal for providing strength and rigidity to the body. A show surface of the weatherstrip assembly is formed of a second metal different than the first metal. The second metal acts as the show surface of the weatherstrip assembly. An isolative, electrically low conductivity layer is received only on portions of the first metal that are disposed adjacent to portions of the second metal and potentially subject to electrical contact therebetween.

A weatherstrip assembly comprising:
- a body that includes, at least in part, a carrier formed from a first metal for providing strength and rigidity to the body, and a show surface formed of a second metal different than the first metal where the second metal acts at least in part as a show surface of the weatherseal assembly, and an isolative, electrically low conductivity layer received only on portions of one of the first metal and the second metal that are disposed adjacent to portions of the other of the second metal/first metal, respectively, and potentially subject to electrical contact therebetween.
A method of isolating a first metal from a dissimilar, second metal incorporated in a weatherstrip assembly, the method comprising:
- forming a weatherstrip assembly body that includes
- providing a carrier formed from a first metal for providing strength and rigidity to the body,
- providing a second metal different than the first metal where the second metal acts at least in part as a show surface of the weatherstrip assembly, and
- isolating those portions of the first metal that are disposed adjacent to portions of the second metal and potentially subject to electrical contact with an electrically low conductivity layer.
