I personally think much below 25% is asking to get at least a second look by the police. Here in TX You can go below 25% for the windows behind the driver and the infamous windshield "EyeBrow" tint. Make a note of the AS-1 Line that is a common reference point for tint laws, most states say AT..XX inches above or below. The problem is the AS-1 Line at least for mine was about seven inches down. Way too much and although legal got in the way of my perepehial vision. I had about 4 inches straight across and seems to work perfectly. I did 25% all the way around to keep a uniform look. (Taurus and Expedition) The Taurus 25% installed in 2015 tinted around 28% Turns out that my 25% (Expedition) actually tinted at around 24% Not enough to look obvious and even the officer said it looked right. You could probably argue tint meter calibration but again it doesn't look obvious as below but you never know when some hick town sheriff has nothing better to do on a Friday night. The rear of my expedition has Privacy glass already installed so when I went to 25% it really came out as around 10% almost LIMO but again no factor since behind the driver. I can see pretty much perfectly even at night. Also remember tint installed at two different parts of the country and different vendors...approximately same time of year although about three years apart.
Mr. Hill....That 35% does look good on the Blue I had the Deep Impact Blue with the same 35%
