Its important to note that the automobile windshield chip repair exterior trim and moldings that we can see on the outside of the glass are for looks only. The actual water seal comes from the "urethane" adhesive which is used to create the bond. Its in this urethane that the water leak is originating.
It's the same thing with a windshield. Why would anyone want to repair a windshield which is the only thing that protects you from oncoming objects to your face? Having a solid windshield in your car rather than a repaired one is probably safer and to me makes more sense.
Of course, fix auto glass is not something that we have to worry about on a regular basis. This is why you probably do not know where to begin finding an auto glass professional. Consider asking some friends or family if they have any one that they could recommend. A mechanic is another good source to find a good quality auto glass company who is going to treat you fair. The good thing about asking a mechanic is that they work with auto glass companies quite often. They know which ones their customers are satisfied with and which ones charge too much money.
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.
Still no big deal? In some states it's illegal to drive with a crack in the windshield that is in the driver's line of sight. In other states it's illegal to drive with a cracked windshield at all. I'd call that a big deal.
So when that stone comes flying down the highway and lands right in the middle of your windshield, be sure to wisely choose your course of action. Save yourself the aggravation and simply repair it yourself. Just make sure you get yourself the right kit!
