I'm looking for someone who has actually tinted the Edge fronts. I can get 15% or 20%. You'll notice a difference between the two. Curious to what you have used. The stock rears/back look different to me in different light.
BTW, I'm in PA where you can't have anything on the front side windows by law but you CAN in fact pass the state inspection. Nice loophole they wrote in a few years back. It's not legal for a cop to pull you over just for the tint but if they get you for speeding, etc. then they could tack it on. That said, I've tinted every vehicle I've owned in the past 16 years and never had a problem. Most cops don't care unless you're a punk kid with 5% tint in a pimped out beater.
Also, 15-20% is no where near limo tint. That's more like 2-5%. Big difference. You won't see out at night with 5% let alone see in.
