For proper bonding between the glass, urethane, and body, what must be done?

• A. All surfaces must be properly cleaned and prepared
• B. Only the glass surface needs to be cleaned
• C. Apply a primer on the glass
• D. Only the body surface needs to be prepared

Answer: (A)

For effective bonding between the glass, urethane, and the body of a vehicle, it is crucial that all surfaces are properly cleaned and prepared. This step ensures that any dirt, grease, or residues that could interfere with adhesion are removed from both the glass and the body surfaces. Proper surface preparation promotes a strong bond, which enhances the structural integrity and safety of the installation. If only one surface (such as the glass or the body) were cleaned while neglecting the other, it could lead to inadequate bonding, resulting in the potential for leaks or the glass coming loose over time. Cleaning and preparing all surfaces contribute to achieving a uniform, robust bond that meets safety standards and performance expectations in automotive glass installations.
