Wow! Looks really good. I have been wanting to do this, but I don't think my state allows any tint on the front or windshield...
You will have to check your states laws. I am in Indiana. They allow as long as it is within the limits of solar reflectance and light transmission. If you have a medical condition that might require it, there is a form that the MD can fill out for even darker. It makes the car look better, protects the interior, protects the occupants from the sun, keeps the car cooler and the helps keep the windows from coming. The owner of the shop claims you can fire a 22 and it will sharer but not come in on you. I have had no issues and driven in KY TN,AL, GA, FL, PA NY DE, DC, VA, WV MI. I asked the tint shop and he said the shops have to know the law of their state.
