I've had a Jeep for 3-4 years that has Raptor lining, in fact that is where I learned about it. It had been sitting at a Hot Rod shop for at least 3 years, so it has 6-7 years on it and never been inside. Still looks great, I must redo because a spot didn't cover well, but was not Raptor's fault. It is tinted Raptor with House of Kolor Molly Orange.

I sprayed mine with Raptor tintable aroud 6 years ago and it has never been inside since and if i hadnt sprayed it with Simple Green to clean it about 6 months ago it would still look as good as it did when i sprayed it. As far as toughness, we wheel hard through brush and anything else and it has held up great. It even stuck when the hood came up and hit windshield at 55mph (hood holds water now)
