There are many excuses that people will use to not take their car in for windshield repair or replacement. It is important to note that many people do not understand the necessity of a strong windshield. Yes, a windshield is what keeps debris from hitting you in the face during the drive. However, a windshield is also an important structural support to the car. If you are in a wreck and the windshield strength has been compromised, you or a family member could be injured much worse than if the windshield was in good shape.
