Abstract
A thin layer of a magnetizable coating is extruded or coextruded onto a external surface portion of a tubular sponge bulb seal for an automotive door or hatch. The coating is of a thickness, location on the seal and formulation to be selectively magnetized to provide a desired magnetic force level to optimize the balance between effective sealing and ease of door opening.
