A molding or moulding is a black rubber, plastic, pvc or vinyl gasket that wraps around the outside of your windshield and helps protect around the outside of the windshield glass and also hold the windshield in place.

When replacing a windshield there is a noticeable gap between the replacement windshield and the body of the vehicle. Most Moldings resistant to ozone, oxidants and severe weather conditions. Moldings also channel water down the sides of the windshield to small drains on the sides of the firewall.
Moldings are applied to the glass prior to installation and when installed properly should lay flush against the vehicle. Since many vehicles are designed with glass edges and pinchwelds being exposed there is a definite need to protect these areas. Moldings should fit snug around the corners of the glass and will protect the exposed glass and pinchweld from outside elements like water, dirt and debris. Some cheap moldings can crack, fade, shrink, discolor or crimp around corners causing air and water leaks or damage to your vehicle.
Moldings on certain vehicles can be removed and reinstalled however other vehicles will require a complete replacement molding no matter what because they can and will crack, rip or tear when trying to remove them. Mercedes, BMW’s, Audi’s are some vehicle makes that require an OEM molding replacement when replacing the windshield on these vehicles.
