DynamicATL, I hadn't even considered receiving fake 3m tint. I bought it from a tint shop online that also sells precut kits. It was really hard to find. The color seems off, the tight radiuses were poorly cut, and it was really hard to shrink. I'd say there's a pretty good chance it's fake. I ordered a roll of the same tint from a different vendor so I can cut my own window. I'll compare the new tint to the first set I got. I should be able to tell if at least one of them are fake. The rest of the car is finished so I'll leave it on and see how long it takes to turn purple.
Thanks for the advice!!
