I checked with a local shop today (nearest Tinworld was too far away) and found out that 35% is our legal limit here in NC. I'll just go with that although he said he would do what ever darkness I wanted. Years ago law enforcement was ticketing a lot aroun here for dark windows but that was the young guys with really dark ones, I don't think they check much anymore but I think 35 will work for me and give my car a better look. $150. for all except windshield. Thanks for the info and I'll be watching for your next mods.
