The reason that cracks often start on the edges of the automobile windshield chip repair is because the edges are the structurally weakest area. The frit is on the glass because it keeps the ultraviolet light from the sun away from the polyurethane seal that holds the windshield in the frame. Without the frit, the windshield would quickly start leaking or just pop out of the frame of the car.
First things first the chip should be repaired before it gets filled with grit. To do this, the chip needs to be drilled while the cracks in it get vacuumed. An acrylic or crystalene resin is then inserted via syringe into the chip to restore the air trapped in the crack. Afterwards it is dried with UV light which hardens the substance and reinstates the original state of the glass. Acrylic resin is made up of carcinogenic acid which turns the chips yellow over time. Crystalene resin has better clarity and doesn't change color over time. It's available at ultra-low consistency and high consistency. Extra resin is scraped away and then polished for a finishing touch. This kind of treatment usually runs about $45-$100.
Of course, front window repair 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.
If you have insurance that will cover windshield repair with a low deductible, this may be a good option. Many companies that specialize in windshield repair will pay the deductible for you provided it's under $100. If you call ahead to make an appointment most of these companies can replace the windshield in less than an hour. If you don't make an appointment, you may have to wait a few hours if there are many customers in front of you.
Stay away from the sun. Park inside a garage when you can and use a protective windshield covering when you can't. If you let heat build up inside the car while you park, you might weaken the windshield and cause the crack to grow.
Not all chips and cracks can be repaired when windshield damage occurs. It is definitely worth the time to have any damage evaluated by a professional to avoid further cracking and damage and eventual replacement.
