Solutions for cracks in the car windshield include: 1. Use a vacuum injector to remove air from inside the glass; 2. Fill the crack with a glass repair agent; 3. Expose it to ultraviolet light for two minutes to solidify the repair solution; 4. Apply a high-concentration repair agent and cover it with a glass piece; 5. Scrape the surface flat with a blade, apply polishing agent, and polish with a cloth. Types of car windshields include tempered glass, laminated glass, bulletproof glass, safety glass, and zoned tempered glass. National regulations stipulate that car windshields must be made of laminated glass, side windows of tempered glass, and rear windshields of tempered glass.
I've been driving for almost fifteen years, and a cracked windshield really depends on the specific situation. If the crack is within the width of a finger and located in the central area, you can take it to a professional repair shop for resin filling. It costs around 100 to 200 yuan and takes about half an hour to fix. However, if the crack exceeds five centimeters or is near the edge, you'll likely need to replace the entire windshield. Don't delay this, especially in hot weather when sunlight can easily turn a small crack into a big one. Last time my car got a small crack from a pebble, it extended by ten centimeters the next day, and I had to spend over a thousand yuan to replace the glass. I recommend going directly to a reputable auto repair shop. After replacing the glass, wait for the adhesive to dry completely before driving, otherwise, it might leak on bumpy roads.
As a mom who often drives to pick up and drop off kids, I would immediately address any windshield cracks. Small cracks can be repaired inexpensively—professional technicians use resin filling to restore the glass strength without compromising visibility or safety. However, if the crack has extended to the wiper area or edges, replacing the glass becomes necessary. Once, my car had a star-shaped crack from hail damage; despite three repair attempts, it kept cracking and ultimately required replacement. Nowadays, many shops offer mobile repair services, which are especially convenient for busy moms to save time. Remember not to slam the car door too hard for two hours after windshield replacement, allowing the adhesive to fully cure.
