I have 5%(limo) on all the windows except windshield. Have had it for almost 3years now. I originally had 20% all the way around for 1year, and then went to 5%. Their is a big difference between 20% and 5%.... it's real nice in my opinion. my 2door 99 accord is white exterior, and tan interior. I'd love to tint the whole windshield 50-70% but I'd be concerned with getting pulled over then.. and also not passing inspection... Houston TX is hot so I am glad the police are not concerned with it as long as I drive appropriately.
