I read 3/4 if the "tint" thread and my question is directed ONLY at the people that have the crystalline tint. I know a lot of people have the photo sync and have been very happy with it. But I'm going to go with the 3M. Anyhow. My question is this...did you notice a huge difference in heat in the he car after vs before? Did you use less AC in the car after vs before? For those of you with kiddos in the he jump seats did your kids notice a huge difference aft you had the tint applied? Considering how much I've pad for this car and all the other mods I've made this is peanuts, but if it's really not going to make much of a difference then maybe I don't need it. I was mostly going to do it for my kids because they are always so hot in the jump seats and th sun shade just isn't cutting it....then secondarily for the savings in miles.
