IT IS A GIVEN I should not have to say that you should go in dressed nicely with some sort automobile windshield chip repair of logo on your shirt or hat that shows you are serious and you are a professional.
Good question. Windshield crack repair equipment varies widely among companies. High quality resins, injections and air removal methods vary from company to company and can affect the finished repair. Quality injection units and high quality resins are as important as the technicians performing the crack repairs. The quality resins create stronger bonds and resist yellowing better than inexpensive resins. Quality injection equipment will remove more air and the injection capabilities provide a higher quality crack repair.
Now that you know what can and can't be repaired, there's one more thing to consider. Time!! Many factors like extreme heat or cold and even your air conditioning cooling down the windshield on a hot day can cause the damage to get worse. The longer you wait to repair the damage, it could spread and may turn a repairable situation into a full blown windshield repair costing YOU more. Most insurance companies WILL cover a rock chip on the windshield at no cost to you. Speak with your insurance agent to get more information on what they will cover when it comes to windshield damage.
Next we have the windshield repair kits priced in the middle. They range in price from $600-$2,000. These are the companies that normally offer high-quality repair kits at a an affordable price. But not all of them.
The windshield is also called a windscreen. Your car's glass is very similar to that of an aircraft, or a motorcycle's wind screen. Most cars made in modern times are usually fitted with a laminated kind of glass that is very secure and safe because it doesn't shatter into sharp shards unlike ordinary glass from mirrors and bottles. These laminated glass is a kind of treated glass. It is usually made up of a dual curved sheets of glass and a layer made of plastic sandwiched in between so that it will be safer. These are glued into the car's window frame.
One way to find out about a companies reputation is to call other repair techs and ask them which company they bought their repair kit from and are they satisfied with it. Call the company itself and ask to speak to the owner. You will get a good feel for the company after having spoken with the customer service people and the owner.
