Black Ceramic Paint Design - Both types of glass will typically have the same exact paint designs around the edges of the glass, although there are a few unique OEM windshields out there. This black design only hides areas from view (ex: under the dashboard, behind side pillars) and it protects the urethane glass adhesive from UV emitted by the sun. UV will degrade the adhesive which will result in the glass falling out or coming loose. One of the few differences found in paints bands may be, the vehicle maker or vehicle model logos embedded in the design. An example is a Ford Mustang windshield. The OEM windshield includes a picture of the Mustang logo above the rear view mirror bracket in the third visor.
