Generally automobile windshield chip repair grow into cracks very quickly. Not taking the vehicle in to get it repaired immediately can result in a crack that is too wide to repair.

The windshield was designed to protect you. The dings and cracks may have come from something that could fly toward you and hit you. It protects you from outside intruders and it helps in the event of a car accident. It is actually designed as the number one safety restraint system in your vehicle. It actually provides up to 60 percent roof-crush-protection in the event that there is an accident where your car flips over. Also, it takes care of backstop support for the passenger side airbag in a front-end accident. This means that the airbag stays in place as a passenger hits it using the windshield to hold it there. So you are protected from being crushed or thrown from the vehicle with the windshield.
If you do decide that automobile windshield chip repair is your best bet, you have a few choices. First of all, make sure you check to see if your insurance covers it. In a lot of instances it does. The problem is that many policies have a deductible that is higher than the cost of the replacement or repair job. If that is the case, you will have to pay for it yourself.
Use your defroster on high. Extremes in temperature are never a good thing for a cracked or damaged windshield. If you live in an area where you are required to use your defroster regularly, gently warm up the car over a period of time. It's also best to find a mobile windshield repair company that can do your repairs as soon as possible.
As you drive down the road, a small piece of gravel can hit your window and leave a chip. No matter how expensive your window is, the glass is still susceptible to chips. Leaving the chip alone can cause breakage and may lead to a full window replacement instead of just having it repaired.
