I hope this isn't the situation, for you, but Previously i had an all black, on black 24" with the windshield done at 10% and the rest 0% (had a doctor note for migranes)...got to a point where I couldn't drive anywhere without getting a ticket.Thanks Man!! I believe its 20%. I told the guys to match up to the rear factory tint as best as possible. I think its just under legal for the state of NC. But never been questioned about it before with other vehicles.
