Went 50% this summer because of MN state laws, instantly regretted it when I went to pick up the car. The shop I had it performed at will waive removal fee and go darker if I get a dr's note. I visited my Optometrist and their office doesn't provide them
The tint shop gave me a few other places to check with which my buddy did and said it was super easy. Thing is, I'm not going to go back and pay for a check-up for another year so I'm stuck for the time being. 20% looks great, but I think I'll go 35% just to avoid the possibility of getting pulled over.
