After a week of testing the nanotech clear tint on my vitara, I can say that I am very pleased with it. It reduced the need for my AC to constantly turn on to keep the car cool. Before I would have to turn the AC to level 3 just to keep the car cool but now after installing nano tech level 1 is good enough for the average daytime sun.

Comparing the heat that gets through the nanotech windshield tint and the old 3m tint on my windows, I can say the heat that penetrates is way less on the nanotech side. Definitely having the old 3m on my windows replaced by nanotech soon so I can enjoy complete coverage.
