It might be hard to tell what this is. When I did the Rhino linings I had the bed off. I was affraid that when i put the bed back on that i would scratch the back of the cab. So I decided to Rhino line the front of the bed and the back of the cab. This worked great, even if I decide to change the color all I have to do is tape to the edge of the lining. No need to paint between the cab and bed anymore.
