Remove the old windshield. Be careful not to damage the paint or bonding surface.Now you should have an empty windshield frame. Use a razor blade scraper to remove as much of the old urethane as possible. Be careful not to scratch the paint or the bonding surface. Don’t worry if you can’t remove all the old urethane, a thin layer helps the new urethane form a stronger bond. Remove any rust spots with sandpaper or a wire brush to prevent it from spreading. Clean up the bonding surface with a stiff nylon brush to remove any loose particles. Vacuum any debris around the area and clean up your work area before continuing.
Use glass cleaner to clean the new windshield perimeter where the urethane will contact it.
Apply a urethane primer to the old urethane and perimeter of the windshield.
Not all urethanes require this step, so be sure to follow the instructions specific for your product.
Lay a continuous and even bead of urethane around the perimeter of the windshield frame.
An electric or air powered caulk gun makes this job a lot easier. If you only have a hand powered caulk gun, place the urethane in a bowl of warm water for one hour before applying.
Fill any gaps in the urethane bead before you continue.
Install the windshield as soon as possible to prevent the urethane from curing before installation.
Use suction cup window holders to lower the new windshield into place, ask a friend to help.
