Automotive Glass Technician Certification Exam Practice Questions And Correct Answers (Verified Answers) Plus Rationales 2026 Q&A | Instant Download Pdf

• Which type of glass is most commonly used in side and rear vehicle

windows?

• Laminated glass
• Tempered glass
• Acrylic glass
• Polycarbonate glass

Tempered glass is heat-treated to increase strength and shatters into small, less dangerous pieces, making it ideal for side and rear windows.

• What is the main advantage of laminated windshields?
• Easier to replace
• Prevents shattering and maintains structural integrity 1 / 4

• Cheaper than tempered glass
• Improves fuel efficiency

Laminated glass holds together when broken due to the plastic interlayer, preventing shards from injuring occupants.

• What is the typical composition of automotive laminated glass?
• Two layers of acrylic with a metal sheet in between
• Two layers of glass with a polyvinyl butyral (PVB) interlayer
• Single layer of tempered glass
• Polycarbonate with UV coating

Laminated glass is made by bonding two glass sheets with a PVB interlayer to absorb impact and prevent shattering.

• Which tool is primarily used to remove adhesive when replacing a

windshield?

• Screwdriver
• Hammer
• Cut-out knife or cold knife
• Heat gun

A cut-out knife is designed to safely cut through urethane adhesive without damaging the vehicle frame or glass.

• What is the recommended curing time for urethane adhesives at 70°F

(21°C)?

• 5 minutes
• 15 minutes 2 / 4

• 1 hour
• 24 hours

Most windshield urethane adhesives require about 60 minutes to reach adequate strength for safe driving at room temperature.

• Which factor most affects the bonding strength of urethane

adhesives?

• Ambient temperature
• Humidity
• Surface cleanliness
• All of the above

Proper temperature, humidity, and clean, dry surfaces are essential for optimal urethane adhesion.

• When should primer be applied during windshield installation?
• After the glass is in place
• Before applying adhesive to the pinchweld or glass edge
• Only on the glass
• It is not required

Primer promotes adhesion between the urethane and metal/glass surfaces, ensuring proper bonding.

• What is a pinchweld in automotive glass replacement?
• The edge of the glass
• The metal flange on the vehicle body where the glass is installed
• The rubber gasket 3 / 4

• The adhesive layer

The pinchweld is the frame around the windshield that receives the urethane adhesive.

• Which personal protective equipment (PPE) is essential when handling

automotive glass?

• Gloves and hearing protection
• Gloves, safety glasses, and long sleeves
• Face shield only
• None

Safety glasses protect eyes from shards, gloves protect hands, and long sleeves reduce cuts during handling.

• What is the minimum safe driving time after windshield

replacement using standard urethane?

• 5 minutes
• 30 minutes
• 1 hour
• 24 hours

Most manufacturers recommend waiting at least 1 hour before driving to allow the adhesive to cure sufficiently.

• Which is the most common cause of windshield leaks after

installation?

• Improper glass tint
• Poor urethane application or incomplete bonding
