This is a chemical treatment procedure that is meant to ensure a proper bond between the vehicle and the glass. Improper cure time remains as one of the most overlooked procedures during glass installation. Proper cure time is relevant to installation materials, humidity, and temperature. If the adhesive is not properly cured when the vehicle is moved, the bond can lose its strength. Some glass installation companies will ask the customer to sign a release or waiver knowing that he or she is probably in a hurry and wants to drive the vehicle.
Some vehicle designs rely on the windshield to deflect the airbag towards the passenger.
If the glass is not properly installed, the airbag can push the glass out of the vehicle, giving the occupants little or no protection. Fred Richards of Amarillo looked back on an episode that brought all the caution warnings to life. I was leaving town and didn't have time to investigate proper glass installation. I had a windshield put in by a major glass chain and it only took them about 10 minutes to do the entire job. They collected my money and sent me on my way.
