Abstract: A weatherseal, especially for sealing a door, a window pane or roof of a motor vehicle, is provided with a base body made of a first elastomeric material. The base body comprises a sealing portion as well as a fastening portion. The fastening portion is joined to an adhesion body defining a materially positive connection of the base body to a component. To achieve good economy by relatively cost-effective fabrication the adhesion body is made of a second elastomeric material having a cellular structure and comprising a contact surface to which an adhesive is applied. Base body and adhesion body are coextruded.
