^ 5% I couldn't imagine on the windshield. I had 35% on 4 of my last cars and it was perfect, not ideally perfect at night but didn't make vision dangerous in any way. Not sure how it would affect the rain sensors as the film will be inside the car but I haven't reasearched the rain sensors and how they work yet. My concern was will it affect the automatic lights which was why I held out on doing it on my TL-S because I wasn't sure if the sensor would think it's darker than it really was.....
Either way I'd like to hear more on this as this is just my common sense opinion.
