I’ve never heard of this before… But anywho, I’ve still got absolutely no plan to tint the windshield… It’ll make it harder for other drivers to see your face, where you’re looking, your hand gestures, etc.
I swear its illegel to have ANY form of tint on the windshield unless its a 5 or 6 inch strip on the top thats to be used as a sunshade (some cars have them from the factory as the blue tint)
