Removing the Damaged Rear Windshield
Step 1: Access the Back of the Car
Open the trunk or hatch to access the interior of the rear windshield. Remove any interior panels or trim if necessary, using trim removal tools.
Step 2: Detach the Interior Molding and Trim
Use plastic pry tools to gently remove any molding, trim, or weather stripping around the glass. Keep these parts safe for reinstallation.
Step 3: Loosen the Old Adhesive
Apply an adhesive remover along the edges of the glass. Use a scraper or plastic pry tool to gently loosen the glass from the frame. Be careful not to crack the glass further or damage the vehicle.
Step 4: Remove the Broken Glass
Wear gloves and safety goggles. Use suction cups to grip the glass firmly. Carefully lift the damaged windshield away from the vehicle, supporting it as it comes free.
Preparing the Vehicle for the New Glass
Step 1: Clean the Frame
Thoroughly clean the surface where the new glass will sit. Remove old adhesive, dirt, and debris using a recommended adhesive remover and a clean cloth.
Step 2: Inspect the Seal Area
Check for damage or rust on the frame. Repair any issues before proceeding. A clean, smooth surface ensures a good seal for the new windshield.
Installing the New Rear Windshield Glass
Step 1: Apply Adhesive
Use a UV-curing adhesive or automotive-grade glue recommended by the manufacturer. Apply a continuous bead around the perimeter of the frame. Follow product instructions closely.
Step 2: Position the New Glass
With help, lift the new windshield glass. Using suction cups, carefully align it with the frame. Place the glass onto the adhesive, pressing gently to ensure a snug fit.
Step 3: Secure the Glass in Place
Hold the glass firmly or use masking tape to hold it in position while the adhesive sets. Keep the vehicle steady and avoid touching or applying pressure on the glass during curing.
Final Steps and Curing
Step 1: Allow the Adhesive to Cure
Follow the manufacturer’s curing time, usually several hours or as specified. Keep the area free of dust and vibrations during this period.
Step 2: Reinstall Interior Trim and Molding
Once the adhesive has fully cured, replace all removed trim and molding. Ensure everything snaps securely into place.
Step 3: Clean the Glass
Wipe the new windshield with a glass cleaner to remove fingerprints and smudges. Avoid using harsh chemicals that could affect the adhesive bond.
