Auto owners seldom think about their windscreens experiencing problems until problems actually arise. With lots of drivers on the road and traffic going crazy, there is a higher chance of your vehicle getting dented. Chips in auto windscreens are common. When driving at a high speed or on uneven country roads, stones, debris or small rocks can hit your front window and cause unwanted damage. In addition, changes in temperature can expand or contract the glass, causing windscreens to weaken over time.
