I have an over the rail factory liner that rubbed the shit out of the top of the bedsides. I cut the tops off when I put my glass on so there's no more over the rail, nothing to rub on. But under the liner, its rubbed the paint off the ribs on the bed. Thought about doing line-x or rhino liner but I'm just too lazy, I'd rather put my new spindles on!
