The Back Window Replacement Process

Step-by-Step Installation Guide

The installation process involves multiple steps, which are crucial to ensure that the new back window is correctly and securely installed:

Removing the Damaged Glass: Carefully cut the urethane seal using a utility knife and remove the old glass using suction cups.
Cleaning the Frame: Use tar removal solvent to clean the bonding surface, ensuring no residue is left behind.
Applying New Urethane Adhesive: Use a caulking gun to apply a new layer of urethane adhesive around the frame.
Positioning the New Glass: With the help of suction cups, lift and position the new window in place.
Securing the Glass: Press the glass firmly against the adhesive, ensuring an even contact across all edges.
Final Checks: Verify the alignment of the glass and clean any excess adhesive before it cures.
