The rubber molding that surrounds a windshield protects the glass edge and helps prevent dirt and debris from working their way into the urethane sealant once the windshield is installed. To install the windshield rubber on most vehicles, however, you must have the windshield off the vehicle. This means that, normally, when you replace the windshield molding, you have to reseal the windshield. Once the windshield is off the vehicle, installing the rubber is relatively easy.
Orient the rubber molding so that the recessed groove is facing the glass edge.
Press the rubber molding over the edge of the glass. Make sure that the glass edge is fully inserted into the groove on the rubber.
Work the rubber around the entire edge of the windshield glass until the glass edge is fully protected.
