Windshield Molding & Weather-Stripping | Safelite AutoGlassDoes it have weather-stripping? The answer to that questions is yes. Most vehicles use some form of molding or weather-stripping of some kind to keep water, air, or debris from getting in your vehicles. The molding is part of the system that seals your windshield to the frame of your car or truck. In fact, there is a weather seal for every auto glass window. Each piece of molding is a long, rubber or plastic notched tube that fits precisely in each of the windshield, window, and body frames.
