It is now easy to get them repaired through advanced technology. Windshield repair dates back to 1960’s, when simple materials like laminated windshield glass were used to do the repairs. In the latter 1970’s improved versions of windshield glass repair with the help of oil based formulas, used as cover up for the damage area of the glass. It was nevertheless very neither efficient nor effective. It must be noted that windshield repair is a delicate yet a very technical task. The windshield is made up of glass layers. Each layer is protects the other. This layering also helps to reduce the splintering in the event of a windshield crash. However, as a result of such a crash air gets into the glass layers and appears as bluish or grayish shade. This is where the challenge for the auto glass repair or windshield replacement technician lies. A new advancement in the windshield repair that helps minimize the flaws of damaged windshields is called ‘prism technology’. Through a specific method used in this technology all effort is made to eliminate the trapped air in the windshield as well as to greatly simplify the entire process. The older system failed to suck all the air out of the injector as all the air trapped in the glass up and through the liquid resin that is contained within the repair injector. As a result, air bubbles would stray back in the liquid resin as the injector is moved in the downward motion. However, in the new technology, the basic method is the same, but with the use of the force of gravity and the creation of a vacuum by attaching a hose to the injector, the injector barrel is turned 180 degrees and the resin liquid runs into the damaged glass, unhindered by air. This vacuum enables the high pressured resin to flow in all parts of the damaged windshield thus, sealing the windshield with the UV light rays, it then is undoubtedly as good as new.
