Carls window tint is the place to go. Years ago when I got my first car tinted I met him at my friends shop, he was doing a job most professionals couldn’t do. He was doing the rear window for a old Corvett stingray. The owner said he went to multiple places that said they couldn’t do it.
He ripped out the tint, laid it out and perfectly made sure there wasn’t a single bubble. They guy was schooled, he didn’t think that could happen and so fast. I have watched him and his team do multiple cars a day years ago before he had a single stand alone shop. This is the place you want to go to get it done right the first time.
On my cars I’m a fan of tinting all the way around. Keep it looking smooth and flowing with your car. It looks blocky when you have the backs tinted stock and not the fronts. To keep it legal on my car I have 35% all the way around and I got the back window a little darker. Since there is so much light coming from the front window if you darken the back a little more I think it makes it look better and is nicer on the highway when trucks are behind you.
On my Jeep Grand Cherokee it has 25 percent stock on all windows but the front and the two front doors. As they recommend it’s hard for your eye to tell between 10 percent. So your safe with anything you want to go with on the front of your car.
All of there products are Suntek. They have a lifetime guarantee as long as your didn’t cause the damage. I have used the carbon series for all of mine. They have two other types but the carbon is the most common. So stop on by.
