Mine will be tinted shortly
Tinting is one of the first things I'm having done. I live in South Florida so it's a must. I want to get reflective tint as it's the most effective, and my last 2 cars had reflective on it and it was fine. But somebody mentioned it may now be illegal in florida, so I have to look into it again.
My old mazda mx6 had custom tinting, I had 35 (I think you could go as low as 20 on reflective legally) percent reflective tint on it so it was quite good and got rid of lots of heat, and during the day it was very hard to see into the car which I liked. But at night when the reflection didn't work as good, you could see in. This is why some people choose to go with the illegal 5 percent limo tinting, as it's so dark nobody can see in at night or day, but it's less effective than reflecting in heat removal. Anyway, I had another 30 percent normal dark tinting put on top of the my reflective tinting (tint on tint), and now during the day it was reflective and useful, and at night it was just as dark (maybe a tad lighter) as 5 percent limo tinting. So I had the best of both worlds, all the qualities of reflective (can't see in during the day, plus great heat fightint capabilities) and limo tinting (can't see in at night). I'm tempted to do the same on my Insight.
Recommendation though, with the tint on tint idea, only do that 2nd layer on the side Windows. It's also dark seeing outwards, so when you get your rear window tinted, you only want to use reflective tinting, don't make it so dark that you can't see clearly straight out your back. I'm thinking I'll go with 20 percent reflective on the back, 35 percent reflective on the sides with a 30 percent normal dark tint on top of that, and a 6" strip in the front. Legally you can only do 6" on the sides of the front window, it curves inwards to be like 4" in the middle of the front windshield, but I always have them make it 6" in the middle, so it's like 8" at the sides. If a cop asks, I'll say the law says 6" so when I installed it I made it 6" in the middle. I didn't know it had to be 6" at the sides. It may or may not work. My car before that, a Honda Prelude, also had pretty dark tinting. I've never been in trouble with tinting in the 5 years I've had it on my cars.
