What have you guys found to be a good window tint. I'm looking for one that will last a while without fading to purple, and is fairly resistant to scratches and stuff. I remember the first time I tinted a window. It was a 3 piece sliding rear window of a truck. I did 2 sections and when I did the 3rd i messed it up. I didn't have any tint left, so I went and got some more. It was a different brand. It wasn't long before the one section with the different tint faded to purple and the other 2 stayed pretty black, even to this day, many years later. Anyone experienced in this field? thanks
