just a point to make- hope I dont sound like a goody two shoes....
in considering 'darker than legal' tint, are you guys mainly worried about the boys in blue defecting you?
because my concern would be insurance worries in an accident- not a defect notice. lets say you pull out in front of someone (or are otherwise at fault in an accident). if it happens to be in the evening or on a day that is overcast and cloudy, an arguement could be made by the insurer that because the car isnt road worthy and your vision was obstructed because of tint too dark to see properly, we will limit (or even cancel) your insurance and make you pay for everything. they are a business afterall, and will look for any loophole to not pay you. will be very hard to fight them on it... its like driving around unregistered (because an unroadworthy car isnt satisfying registration requirements anyway) . just a thought, I'll go back in my box now.
