DO YOU KNOW WHAT THE BLACK DOTS ON THE EDGE OF THE WINDSHIELD ARE FOR? The answer will surprise many drivers
Although you see them every day as soon as you get behind the wheel, you probably never thought much about those tiny black dots that follow the edge of the windshield.
TL;DR
- The black dots and band on windshield edges are called frit, a ceramic paint layer fused to the glass.
- Frit protects the windshield adhesive from UV radiation, preventing weakening and potential detachment.
- Its rough texture enhances the adhesive's bond to the glass.
- It aids in even heat distribution during glass manufacturing, preventing optical distortions and damage.
- Frit aesthetically conceals adhesive marks for a cleaner look.
- The dots in the upper section act as a fixed sun visor, reducing glare for the driver.
