Tinted Atmospheres in Cary. I just had David tint my car a couple weeks ago. 35% Llumar (ATX?) on the sides/back and AIR-80 on the front. The front tint is clear ceramic and cuts down on the heat coming through the windshield more than the metallic tint on the sides/back is capable of. Very noticeable difference in heat - I'd say easily 50F+ cooler when the car is sitting in the sun in a parking lot. I've been driving around today with the AC on but on 1 bar instead of the normal auto (4-5 bars) because it doesn't have to work as hard when the car is already relatively cool when you get in it. Not bad for a humid 85 degree day.
They have a heat lamp in the shop so you can feel the difference in heat reduction from the various tint types.
FYI his brother Jordan owns Import Motor Werks across the street but I didn't get a chance to go by and visit them yet. I know some other people on the board have though.
