A weather strip seal for an automotive vehicle is provided including a generally rigid carrier reinforcement for retaining the shape of the weather stripping; a first ionomer material extruded onto or carried by the carrier, the ionomer material having a glossy surface; and a second elastomeric material extruded onto the carrier, the second material being provided for sealing between a first structure the weather stripping is attached to and a second structure.

DETAILED DESCRIPTION To make manifest the above delineated desires, the revelation of the present invention is brought forth.
In a preferred embodiment, the weather strip of the present invention provides a generally rigid carrier reinforcement which retains the shape of the weather stripping.
Although a plurality of materials can be utilized, a metal such as stainless steel is typically found to be preferable.
Extruded onto the stainless steel carrier is an ionomer.
The ionomer has a black or color surface finish in various degrees of gloss.
Co-extruded or carried upon the carrier is an EPDM rubber portion.
The EPDM rubber provides a substance with excellent sealing requirements.
If appropriate, the EPDM rubber can also have flocking added to reduce friction against moving closure members such as windows.
The weather stripping of the present invention is particularly useful in applications of an outer belt seal and decorative strip along the vehicle door for the movable window which is encased within the door envelope.
The present invention also finds special application in sealing the door frame against the vehicle door opening.
Other features and desires of the present invention can be discovered by a review of the accompanying drawings and detailed description of the preferred embodiments.
