The only issue I had was after laying the new carpet down I had a hell of a time getting the back seat bottom in. Other than that the stuff is easy to work with. I didn't line the inside of the doors because I read where sometimes it didn't stick very well and sort of peeled off and ended up in a pile in the bottom. I guess sometimes it doesn't work very well vertically unless there is something to hold it there like an interior panel. The only thing that I may go back and do something with is you can see it in between the gap in the top and bottom rear seat when it's folded down. Looks kind of funky. Might have to take some black spray paint to it so its not so noticeable.
