3 Answers
Solutions for cracks on the car's windshield include: 1. For minor cracks, use a specialized glass repair agent to fill them, which does not affect the original glass structure and function; 2. For longer cracks, the windshield should be replaced. The functions of the windshield are: 1. To shield against wind and rain, and reduce noise; 2. To lower wind resistance and direct airflow; 3. To protect the safety of passengers. The replacement method for the windshield is: 1. Remove the black protective strips around the windshield with a screwdriver; 2. Use a steel wire to pull away the sealant around the entire windshield; 3. Scrape off any remaining black sealant on the car with a small blade; 4. Apply polyurethane sealant to the windshield frame; 5. Install the windshield.
If the windshield suddenly cracks, I will immediately pull over to inspect it, as it's not just an aesthetic issue but a major safety concern. I recall in my younger days when I neglected a small crack while driving, which rapidly expanded on the highway, nearly causing the glass to shatter and almost leading to an accident. The windshield is part of the vehicle's structural support, and cracks can compromise its strength and visibility—especially dangerous when directly in the driver's line of sight. My advice: first, park safely and assess the crack. Those under 10 cm can usually be professionally repaired for a few hundred yuan, with results nearly restoring the original condition; larger cracks require full replacement, potentially costing thousands. Avoid DIY fixes like glue or makeshift solutions—they’re unsafe and ineffective. Also, check your insurance policy: many comprehensive plans cover glass damage but require reporting within 48 hours. Act promptly—safe driving outweighs everything, and ignoring cracks only escalates risks.
When encountering a windshield crack, I handle it step by step: First, find a safe place to park and inspect it, avoiding high-speed driving to prevent vibrations from expanding the crack. Take photos for insurance claims or repair reference. If the crack is small, drive slowly to a professional repair shop; for large cracks, contact towing services. The repair process is straightforward: technicians inject resin into the crack to solidify it, filling the gap like mending clothes, done in half an hour at a low cost. However, if the crack is long or in a tricky spot like the edge, a new windshield is needed. After replacement, wait 24 hours for the adhesive to dry before washing the car. Maintain a safe distance from trucks while driving to reduce stone impacts. This experience taught me not to procrastinate—early repairs mean lower costs and higher safety.
