Take a look at almost any modern car, and you'll notice a band of black paint running around the edge of the windshield. Just inside that border, the solid black strip gradually fades into dozens—or even hundreds—of tiny black dots.
Most drivers never give them a second thought. But those dots, known in the auto industry as the "dot matrix" or "frit dots," serve several important purposes. Without them, your windshield would be more prone to stress, the adhesive holding it in place could degrade faster, and your car might not look nearly as polished.
