There are not many QUALITY tints there. For ceramics - Pinnacle Formula One and Huper Optic. Then there are Madico Wincos and 3M Crystalline. They are not a
ceramic or metallic, but a nano multi-layered films that perform exceptionally. The only downside to Wincos is the slight blue hue you see from the inside, and the greenish hue you see from the outside.
Llumar ATX are not bad, bit just a notch below Pinnacle Formula One (which is also owned by Llumar).
I'm yet to get my car tinted, and I'm kind of a person who likes to research it a lot
Huper Optic does have good specs, but it is a lot thicker than any other film (the lower in %% you go, the thicker it gets), and proper installation plays a huge role. I've read very mixed reviews on Huper Optic. You either love it or hate it. It may have an excellent heat rejection, but I don't think I want to take a risk to end up in "hate it" group. Also, Huper Optic tint is
ceramic like the Pinnacle, but it has been determined to be significantly more conductive than Pinnacle. That conductivity can cause radio reception issues and other interference problems.
So I'm choosing between Pinnacle Formula One and 3M Crystalline.
There is only one authorized Formula One installer in my area and a few 3M installers. Installation of 3M is more expensive, but not by much. Pinnacle will make the windows look darker than 3M, and on black/black car any tint will appear darker even if going legal limit.
I'm still contemplating whether I want to put anything on the windshield. If so, then only 3M Crystalline or Llumar AirBlue, as both make almost transparent tints. MD only allows 5" strip on the top, but in my opinion having tint on the windshield will play a big role in total heat reduction. I've read that on some windshields the tint may distort the view, thus the hesitation.
Here are the specs for both tints.
1. Solar Energy Rejection
2. UV Rejection
3. Visible Light Transmission
4. Glare Reduction
5. Visible Light reflection
6. Infrared Rejection
