A seal assembly includes a body portion defining a mounting channel for receiving a vehicle flange. A base of the body portion defines an outer surface of the body portion with the outer surface defining a first axis of curvature adapted to correspond with a contour of the flange. The seal assembly further includes a sealing lip portion co-extruded with the body portion and defining a notch having a notch configuration, an element disposed in the notch and pre-formed to have an element configuration corresponding to at least a part of the notch configuration, and a molding material molded to a back surface of the element, secured to the sealing lip portion within the notch, and extending across the notch, with the element and the molding material defining a contour lip portion that in combination with the sealing lip portion defines an external sealing lip of the seal assembly.
