Window tint options for heat rejection

[i6pwr]

I'm looking at either Llumar IRX or Autobahn Ceramic i3.

The Autobahn is 3 layer and I'm concerned about optical clarity, especially at night. I have had good luck with Llumar in the past but never used IRX, so I'm curious about the i3.

My goal is for maximum heat rejection while retaining clarity. My gut says Llumar IRX and the heat rejection difference would be negligible...curious to all opinions.

I wouldn't worry about layered film, the 3M Crystalline on the GLI is layered and has been optically perfect for the past 8 years. I know the Llumar IR has a very high heat rejection without having to be very dark. Llumar's Air Blue 80 line is also a very high heat rejection film with hardly any change in light transmission. I have this on my Tiguan's windshield. Even though the cabin is all black, it stays tolerable inside during sweltering temps.

Mine was installed at the Mercedes dealership. I went legal, but for heat rejection, you'll need to go a step darker. I'd hate to think how hot this car could get in FL without any kind of tint.
Night and day vision is unaffected, and passersby can see me fine inside the car. Such as if I motion them to go while stopped. So, there is an advantage to legal, just don't go too dark.
