While I understand where you're going with that, I think this is very rarely an issue. As I type, I'm trying to consider how often I use what I see in the driver seat as a way to anticipate... I could be in the minority though. I'll don my own suit.

 

Go with 3M Ceramic IR, or 3M Crystalline if you want to spend more. I think 40% is more than adequate and others can still see you.

The heat rejection is phenomenal.

 

I agree with the above. The type and quality of tint is more important than the darkness when it comes to heat rejection. A high quality ceramic tint in a very light shade can block way more heat than a dark non ceramic film. That said, I have 20% ceramic on my front doors to match the rear and 50% on the windshield. Technically not legal but I fortunately don't have any "tint police" around here. They will pull you for something way more severe here, might cite the tint when pulled over for something else.

 

Good point here. The rear windows and the back glass come 'darkened' from the factory, but are not tinted to provide any UV protection. They still need to be covered in film to reduce heat and prevent sun fading.

Just tinting the 2 front windows to match the color of the rear is like closing one barn door, and leaving the other open...

 

Yep I believe Ford calls it "Privacy Glass."

 

To answer your original question: you can tint the roof as dark as you want. I have 40 on the front 2 windows and 5 on the rest and you can tell it’s tinted and more importantly it keeps things cooler, keeps the sun off my kids, and hinders people from looking in.

nobody needs to see me or make assumptions on what I’m gonna do based on my body language, vehicles are equipped with all that equipment on the outside of the vehicle. Plus, nobody needs to see that my wife is driving alone or driving with 2 kids.

 

For those who have tinted the front windshield...do you have any issues at night with reflectivity? A friend of mine had a Tundra a few years ago with the front tinted and at night it was like being in a mirror-ball...VERY distracting, every single dash/interior light was reflected.

 

one of the best things I did to my truck was tint the pano roof, I went from NEVER opening the shade due to glare and heat, now I never close the shade. I love the view, it is tinted to 5%. No more glare, no more heat, shade stays open all the time.

NJ is sensitive to tint, I have 50% on side windows and 80% on windshield.

 

No issues, actually cuts out the glare from oncoming traffic and street lights. Have your buddy dim his interior lights lol.

 

I dont have this problem with 80% ceramic on front. But its great to no longer have glare, and heat from low sun cooking your t-shirt as you're driving, and it keeps the cabin a lot cooler.
