Ive done some on my truck. Its nice when it works the way you want it... when it doesnt it gets really frustrating. I spent almost 3 hours trying to do the bumper on my truck, after boiling over with frustration i ripped it off and threw the rest of the roll in the basement lol. I did do the interior trim in my truck with it, and it was easy being mostly flat. Thats just my experience with it.
