Well, to answer the question... Here in MO there is a limit on how dark you can go on the front windows. It is 35% in the front. Just like my ride! You can go as dark as you want in the rear. As for the windshield. There should be a little mark on the passenger side. Here in Missouri, you can only go as far as that mark.
Im working with 5% tint all the way around here in florida. Also the guy who tinted my windows has Triple Tint all around his single cab of his 04 SRT but its a high clairity tint like mine. I can see out at night with no problems! i plan to also tint the front window 5% when i switch over to Florida plates. People keep telling me cops like to mess with out of state plates, so im not giving them a reason just yet!
