The Drive

The little black dots found on car windshields are actually part of the manufacturing process. They are a result of a type of plastic welding known as "dot-welding" and are used to bond the windshield glass to the frame of the vehicle. The dots help to provide structural strength, reduce vibration, and protect against water and other elements. The dots also act as a visual guide for technicians when performing maintenance on the windshield. In short, they are an essential part of the vehicle's overall structure and function.
