Can a cracked windshield from a stone impact be repaired?
3 Answers
Small cracks in the windshield can be repaired, but large cracks cannot. If the crack is in the primary viewing area, repair is also not recommended. Hazards of windshield cracks: While driving, the pressure on the windshield increases with speed and wind velocity, causing the crack to expand. This can impair visibility and compromise driving safety. Crack repair method: Clean and wipe the cracked area thoroughly, ensuring removal of any debris in the crack to avoid leaving marks after repair. Align the center of the suction cup base with the repair position and secure it. Attach the pressurizing device to the suction cup base over the repair spot, then unscrew the upper pressurizing rod after confirming proper alignment. Pour the repair fluid into the top opening of the pressurizing device and screw the rod back into the base. Wait for the repair fluid to penetrate and cure (approximately 10 minutes), then unscrew the rod, wait one minute, and screw it back in to remove air from the crack. Finally, remove the observation plate and repair device, and scrape off any residual repair fluid with a blade.
A few days ago, my car's windshield was also cracked by a stone. After consulting a professional technician, they said small cracks can be completely repaired, which was quite reassuring. Generally, cracks shorter than 2 cm, not extending to the edge of the glass, and not old can be fixed with special resin filling. The repair process is simple: the technician will clean the crack, inject resin, and then cure it with UV light. It takes about twenty minutes and costs around a hundred or two hundred yuan. From my observation, if the crack is large or directly in the driver's line of sight, the repair might not be as effective, and the entire windshield would need replacement, which could cost several thousand yuan. The key is not to delay, especially in hot weather or when driving on bumpy roads, as the crack can expand. Getting it repaired quickly at a reliable shop can save a lot of money. After repair, the crack is almost invisible, doesn’t affect safety or vehicle inspection, making it a worry-free choice.
I remember last summer when a stone cracked my windshield on the highway. The crack wasn't too big, about the size of a fingernail, so I went straight to a repair shop. After inspection, they assured me that a repair was completely feasible. The method involved using a special adhesive to penetrate and seal the crack. The whole process was quiet and quick, costing less than 300 yuan. If left unattended, the crack would have grown longer, eventually requiring a full windshield replacement—a much more expensive solution. After the repair, the glass regained its original strength without affecting visibility or causing any future issues. My advice: don't hesitate to address small problems promptly. Unlike my friend who waited until the crack worsened and suffered unnecessary losses, it's wiser to act early. Also, maintaining a safe distance from large vehicles while driving can help minimize such risks. Protecting your windshield not only ensures safety but also saves money in the long run.
