i have 5% all around on my civic (except the windshield). at first i loved it, but i hate it now, its too **** dark for me to see outside. it gets dark at 5:30pm outside now and sometimes i have to roll my windows down so i can see out of them! i also cant tell whats going on behind be unless i see lights, so backing up is hard at night.
i'm going to strip it off and put something a little lighter on it, 15% or 20%.
i have had the 5% for 1.5 years, never been pulled over because of it (but i have never been pulled over anyways).
i would highly recommend NOT getting 5% on the front windows, and maybe not in the back either, but definately not the fronts.
