The black dots, called a “marvel of engineering” by experts, are often overlooked,
They are part of the frit band, a rough-textured enamel paint strip that frames the windshield’s edge. This band plays a pivotal role in securing the windshield to the vehicle by providing a better grip for the glass and glue.
Additionally, the black frame acts as a sun guard, protecting the adhesive from the damaging effects of ultraviolet rays. It prevents the adhesive bond from weakening due to constant exposure to direct sunlight.
