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.

[ What is claimed is:] [1.]1. A method of making a magnetic seal for an automotive vehicle comprising the steps of:(a) extruding an elastomeric sealing element having a generally U-shaped carrier for securement onto a flange and a tubular sealing element;(b) extruding onto a minor, limited surface area of said element, a thin layer of an elastomeric material having a magnetizable material dispersed throughout the thin layer; and(c) magnetizing said thin layer.
