I had my car tinted and for those that wanted to know what the meter read on the privacy glass windows, it was 24. I installed Llumar CTX 35 for the front and passenger driver windows and decided to go with the Llumar AIR 80 BL clear for the privacy glass side and rear windows. My concern were tint laws in my state and visibility at night. 35 +/- 6 for the fronts and the rears you can go as dark as you want. I didn't see the meter but the installer told me the rear tints went down to 20 when I came to pick up the car.
