Well, it took me long enough to make up my mind but I had all 10 windows tinted today.
The windshield was the one I was stumped at, how to get the UV and heat rejection on that big piece of glass.
The other criteria was to stay legal here in CA and not to look too dark, like a Limo and also to have the whole job match.
For professional advice I went to the oldest and best rated window tint shop in my area and was finally able to make a decision.
They installed LLumar Formula One Air Blue 80 Ceramic tint on every window. At one point they had 4 guys working and the job took 2.5 hours, all hand cut.
These guys are pro's and did a super job.
On the way home in today's 100F heat I was able to rest my arm on the driver's side window ledge and felt no heat from the direct sunlight.
The dashboard was merely warm to the touch, it used to be hot. This tint has blocked almost 1/2 of the heat entering the car.
Visibility out the windshield was excellent, it is a very subtle tint looking from inside out.
I am very pleased with the conservative look, the spec's for this tint are here.
This is an expensive ceramic tint material compared to the older metallic tint. It also does not interfere with cell phone, GPS or other electronic signals from the car.
I had to get out my good camera because the iPhone camera's filters made it look almost black, and it isn't.
These pictures are pretty close to what it is.
The interesting photo is the one of the open door, looking from inside, the tint is very light from the inside, so driving at night isn't going to be a visibility problem.
