Experts praise the black dots on automobile windshields as a technical marvel that are crucial to overall performance while being frequently ignored. These dots are a component of the frit band, a textured enamel paint strip that surrounds the edge of the windshield. This band is essential for improving the grip of the adhesive and glass, which guarantees the windshield is securely attached to the vehicle.

 

In addition to serving as structural elements, the black dots cover the glue from UV rays that could be harmful. This protection stops extended sun exposure from degrading the adhesive bond over time.
