Full Answer

To remove the plastic trim or rubber molding from the vehicle's windshield, use a screwdriver with a flat head. You may need to cut out the rubber molding. To remove the urethane molding, cut it using an automotive cutting knife. Break the seal and apply gentle force to take the windshield out.

Reduce the size of the residual molding to 3 millimeters by scraping with a razor blade. Remove loose molding and any other debris with a wet brush and clean the pinchweld. Allow this area to dry, and then apply a layer of urethane using an electric caulk gun. You can apply the new urethane layer over the old one as long as the latter is just 3 millimeters in size.

Next, apply a coat of urethane primer on the frit band of the replacement windshield. The primer activates the band so that it sticks to the urethane layer. Avoid touching the frit band with your hands, or use nitrile gloves when working to avoid interfering with the activation process. Finally, position the windshield so that it is aligned with the frame, and ensure that the urethane layer and frit band make good contact.
