Black dots on top of windshield?
Hey you all, what are the black dots on top of the windshield from the inside? I have a strip of purple tint I WANT to take off desperately since I re-tinted my rear window to 5% in the back and 35% on the sides. Finally got rid of the cheap purple crap! I took off the tint fine, but haven't touched the window strip. Couldn't be the antenna I'm assuming, but could it be part of the defroster or not? Or are they just there? I screwed up my first car when I stripped it off and it screwed up the radio signal (sold it like that and owner is probably pissed lol), but don't know if the one on the ram is for some type of shading or part of the defroster. Please respond before I rip it off improperly! I'm too lazy to go down to my parent's house to borrow a steamer. Thanks!

RE: Black dots on top of windshield?
Windshield glass contains a black enamel band (called the frit) around the periphery that is baked into the glass. This black band includes a border of dots. See figure. The band has an etched surface to enable adhesive to bond to the glass, says a sales manager at Able Auto Glass. When car manufacturers install the windshield, they bond the windshield to the vehicle with adhesive placed on the etched part of the black enamel glass area (inside surface). The outside of the enamel band shades the adhesive from the Sun and protects it from ultraviolet radiation. The band also serves a cosmetic purpose by covering up the adhesive and gives the windshield edge "a more finished look."
