On the off chance that you invest a great deal of energy looking directly ahead while stranded in rush hour gridlock, you might have considered what those little dark dabs circumnavigating the edges of your vehicle’s windshield are.

“The frit band likewise acts to give a harsher surface to that cement to adhere to, and it’s a visual boundary, keeping individuals from seeing that dreadful paste from outside,” David Tracy composed for Jalopnik. The frit has been typical since the 1950s and ’60s, when vehicle makers began trading out metal trim for glues.

To lessen optical twisting because of this warm dissimilarity, a speck slope is utilized to level out the temperature.
