I have 5% all around but windshield and I have passed all my cars with it.
Just need to develop a repor with the shop, offer them 50 bucks, or go in with the windows down haha.
And if a cop asks you where you got it done, say you don't remember, or a shop out of that city.
Is this fool proof? No. Have I just been lucky? Yea probably. (Til you look at my ticket record haha) but there are ways around tint laws.
