I've currently have Intersolar tint on my 2 front windows and windshield strip. But, I only bought this tint to use as practice tint. I wanted to try with a tint that was at least a 2 ply. Its packaged poorly in a tube, and the tint is not placed on a roll so its not easy to unravel if you're alone. I've had it on for two weeks but who knows how long it will last, I really don't care. Its just for practice.
