So far we've had zero issues with it lifting off on the trim or the doors (knock on wood), but we were thinking about trying some kind of a clear coat over it for UV protection and because I don't know a way to clean this if it gets dirty without risking the glue underneath. But since it's in my GF's car and not mine, I keep forgetting to look for something to use LOL
I had tested a scrap piece with just some plain old clearcoat, but all it did was soak in and make the fabric feel terrible to the touch. I might look into like a gel coat, like something you'd use over CF...I dunno, I don't know anything about that stuff yet
