I've used Huper Optik ceramic tint on all windows including the windshield. The windshield was tinted at 80% and I can't notice any issues at all driving at night. I have to also add that tinting the Prime's windshield makes a HUGE difference in how fast the interior heats up after the car is parked. It also allows the air conditioning unit to work at a much lower setting to keep the car cool. As for questions about replacing the tint - my insurance company (State Farm) replaced both my cracked windshield and tint without any questions. This was a good thing since my windshield tint cost upwards of $500.
