A weather strip seal is provided for sealing between first and second structures, and a method for manufacturing such a strip seal. The weather strip seal includes a main leg made of a polymeric material, having one side and another side and terminating in first and second ends, a first sealing portion designed to press against the first structure and extending on the one side of the leg adjacent the first end, and a metal carrier for retaining the shape of the strip seal which has an asymmetrical substantially U-shaped cross-section having a first branch reinforcing a portion of the main leg and a second branch extending from the second end on the another side and terminating in a second sealing portion designed to sealingly press against the second structure. An ionomer tie layer is located between the metal surface and the at least one polymeric material.
