20 percent

 

I tint windows for a living, I'm still working on my EVO when it will be done I will tint it with 15% on all the windows and 35% on Windshield like I have it on my STI now. I actually been pulled over few times, fine in CO would be around $100. It's worth it tho,,, lol, keeps the car cool.

PS: krazirob it's old thread but still a comment on ur post, u are right about the 3M window film, it comes off the windows with the glue, which can be bad on on some cars with tight moldings and hot summer day, but I love working with it, make my job a lot easier.
