In Wisconsin, the states up to 35% for the back window and rear side window, and up to 50% for the front side windows.either 20 or 35. 35 is the law around here but idk how much they enforce that. ive seen people with limo tint.
Nope, don't use any ammonia based cleaner. Go to an auto parts store and get a tint film safe glass cleaner. Should only be about $6-10 for a large spray bottle.I have 20% and it's 3M. I like it.
How to you clean windows with tint though? I don't think I can use Windex.
