So I'm going to have my Model X windows tinted. The side windows will get a tint, as will the front windshield (but a lighter shade) as the factory tint isn't strong enough for the San Diego sun. My tinter will have to order a special large roll for the front windshield. Anyone have an opinion on how good the back windows, top roof, and back hatchback factory tints are? I'm wondering whether or not to put a light tint on them as well for more heat rejection.
