Can cracks in the black area of the windshield be repaired?

Cracks in the black area of the windshield cannot be repaired. Functions of the black area: To block sunlight and prevent glare when looking at the rearview mirror. Since a sun visor cannot be installed behind the rearview mirror, this area serves that purpose; For electronic camera focusing. This area is designated for camera focusing, as required by traffic regulations; To prevent the glass from cracking due to uneven thermal stress during intense sun exposure. The edges of the glass are directly attached to the car body, while the central areas are transparent, absorbing less heat than the edges. The black dots ensure even heat distribution across the glass, preventing cracks. Laminated windshield: This refers to a type of glass where a transparent adhesive plastic film is placed between two or three layers of glass, combining the toughness of plastic with the hardness of glass, thereby enhancing the glass's resistance to breakage. Upon impact, the glass breaks into small, blunt-edged fragments, reducing the risk of injury to passengers.
As a veteran driver with over 20 years of experience, I've coincidentally encountered similar issues. Cracks in the black area of the windshield are actually quite common, especially when hit by stones on highways. The black portion is usually the edge's shading layer, and small cracks, such as those under 3 cm in length, can be completely repaired. I had one repaired before—a professional shop injected resin into it and cured it with UV light, making it virtually unnoticeable, all for 300 yuan. However, be cautious about the location. If the crack covers sensors like rain sensors or cameras, repairs might interfere with their function, in which case it's best to replace the glass entirely. The black area itself is a ceramic coating, not a structural core, so minor repairs are safe. Still, don't ignore it, as temperature changes can cause the crack to expand. I recommend getting a professional evaluation as soon as possible—don't delay, as driving safety should always come first. Also, remember to check your insurance coverage, as some comprehensive policies cover glass damage.
