What’s the Black Band Around My Windshield?

The strong adhesives in today’s windshields are also UV sensitive and therefore require a black band around the perimeter to protect it. This also mean the band heats up in the sun more than the rest of the windshield. But keep in mind hot glass cracks quickly if there is a chip near the heat. Just think of all the times you have watched a chip or crack spread in the winter when you turned your defrost on.
