Correct removal technique minimizes the risk of cuts and injuries from
broken or shattered glass during removal.
2. What type of adhesive is typically used to bond automotive glass to a
vehicle frame?
A. Silicone caulk
B. Rubber cement
C. Urethane adhesive
D. Epoxy putty
Urethane adhesives are formulated for auto glass installation due to their
strength, flexibility, and ability to bond glass to metal surfaces.
, 3. Before installing a new windshield, the pinch weld must be:
A. Painted
B. Cleaned and primed if required
C. Covered with tape
D. Heated to 200°F
Proper surface preparation with cleaning and priming ensures optimal
adhesive bonding and structural integrity.
4. What is the minimum recommended wait time for urethane
adhesive to cure before driving the vehicle?
A. 10 minutes
B. 30 minutes
C. As specified by the adhesive manufacturer (often 1–4 hours)
D. 24 hours
Cure time varies by product and conditions, and following manufacturer
specifications ensures safe drive-away strength.
5. When cutting out old adhesive from a vehicle frame, the technician
should use:
A. A dull razor blade
B. Specialized removal tools (e.g., cold knives, wire)
C. A hammer and chisel
D. Sandpaper
Proper removal tools help avoid damage to the vehicle frame while

B. To lubricate the glass
C. To promote adhesion between the urethane and the glass surface
D. To clean contaminants
Glass primer improves adhesion of urethane adhesives to the glass,
ensuring a secure bond.
8. Which personal protective equipment (PPE) is essential during
windshield removal?
A. Flip-flops
B. Safety glasses and cut-resistant gloves
C. Earbuds
D. Board shorts
PPE such as safety glasses and cut-resistant gloves protects the technician
from flying debris and sharp edges.
