I have a 2012 F-150 Lariat and just got the windows tinted. The back came out fine, but the front looked discolored. I took it back to the place that tinted it and they retinted the front for me and it turned out the same. They said it was a problem with he hue of the glass. They used Llumar tint. I believe they did 15% in the back to match a 5% in the front. Has anyone had a problem similar to this? Could it be the tint that they used or is it actually the window? They said they did another F-150 and it turned out the same way. Picture below.

 

I'm guessing its the tint. Got mine done last week and it looks great.

 

because the back has two layers of tint, the factory inside the glass, and the aftermarket on the outside of the glass.
