Can a Windshield Be Repaired?
2 Answers
Windshields can be repaired, depending on the length of the crack. The repair method varies based on the situation: 1. For minor cracks, a specialized glass repair agent can be used to fill them without affecting the original structure and function of the glass; 2. For longer cracks, the windshield must be replaced. The cleaning method for windshields is as follows: 1. Start by pouring water from the top of the vehicle and use a sponge to wipe away dirt; 2. Spray a glass cleaner solution evenly onto the glass using a high-pressure spray bottle; 3. Carefully dry the surface with a soft cloth. The functions of an automotive windshield include: 1. Protecting against wind and rain while reducing noise; 2. Minimizing wind resistance and aiding airflow; 3. Ensuring the safety of passengers inside the vehicle.
Of course, small windshield damage can be repaired—I handle this kind of thing often. For star-shaped cracks or short cracks caused by small stones, with a diameter of less than one inch, professional resin injection can fix it. The process is simple: clean the crack thoroughly, inject special epoxy resin, then cure it with a UV lamp for a few minutes, and polish it—it’ll be barely noticeable. After repair, the strength is restored without compromising safety. However, if the crack is in the driver’s line of sight or larger than a coin, repairs may not be effective, and the entire glass must be replaced. Otherwise, over time, temperature changes or vibrations can cause the crack to expand, eventually affecting driving safety. The repair cost is usually between tens to a little over a hundred yuan, saving a lot compared to a full replacement while avoiding potential sealing issues. I recommend fixing small cracks immediately—don’t delay.
