ABSTRACT:
A method of producing a weatherstrip for an automotive vehicle is included. This weatherstrip includes generally a sliding seal portion for sealing between a vehicle body and a window glass and a weatherstrip base portion for bordering an open edge of the vehicle body. The sliding seal portion is made of rubber material with which lubricant is blended so that the lubricant bleeds out of an outer surface of the sliding seal portion with use for providing low friction against sliding movement of the window glass. The weatherstrip base portion is made of conventional rubber material including no lubricant and is one-piece molded with the sliding seal member by extrusion molding.
