Many drivers faced such a nuisance as the appearance of a crack on the windshield of their favorite car. A crack that appears will surely irritate the driver and irritate his eyes, and in the event that it continues to grow, such a phenomenon can no longer leave anyone indifferent.

Step 1
In addition, under the terms of the new technical regulations for vehicles, it will not work to undergo an annual inspection with any crack on the windshield of a car. Because such defects to a certain extent reduce the safety of driving.
Step 2
Thanks to innovative technologies, motorists no longer need to replace the windshield due to the appearance of defects in the form of chips and cracks, which are currently very successfully undergoing refurbishment using composite polymer materials that have the same refractive angle as glass. Sveta.
Step 3
Modern car windshields are made by gluing three layers; two - glass, and one: between them - polymer. Therefore, at the initial stage of repairing a crack that has appeared on the windshield, the layer in which it formed is determined.
Step 4
Then, if a single crack is being repaired, then its beginning and end are drilled only in the layer in which it is located, without affecting other layers of the windshield. If an asterisk has formed on the surface of the glass, holes are drilled at the ends of all its rays. And in cases where the crack has damaged all layers of the windshield, then it is drilled through.
Step 5
After making holes to prevent further crack propagation, the existing defects are sealed with a polymer compound, and then the glued glass surface is manually polished. This technology returns up to 96 percent of the original transparency of the glass.
