Yup... got the tint put on today and it turned out great (as far as I can tell).
I put 20% on all sides (front & rear) and 35% on the rear(so it's still visible when backing up). It looks real nice. I know 35% is legal here and I'm hoping not to catch too much attention with it but I hear SUVs are given a little more slack with tint. I also have a friend with a Tahoe... and has all 20%s and he's never been pulled over.
I guess it's just personal preference if you wanna take the chance or not. If you decide to go with 20% just take extra caution when driving at night and when in doubt, power down the windows.
And yes Kemosabe... Blue is correct but maybe we shouldn't be discussing it here
I'll try to attach a pic within the week if anyone's interested.
