Here's a couple more for you in different light. I am happy with the 35% all around (minus the windshield, tried to keep it somewhat legal). It's Pinnacle 35% ceramic tint. I got it done at LA Tint in Manassas, VA. I've read here someone that complains that ceramic tint messes with the CA and stuff, but that is not the case, at least it isn't with me. I have no electronic issues at all with ceramic tint.
