I have the new future of tint on hand. I have 4 different types of Ceramic tints. What is working best is the carbon ceramic tint. It has the best heat rejection AND long life ability. It is the most optically clear or no vision distortion and won't fade. Some of the ceramic tints out there are combined with dye to get more pigment. Those are both going to fade and not have as much heat rejection as you can get. Here is a video explaining the ceramics. Enjoy..
