I spray n liners for a living Speedliner to be exact and some of the answers above might work I have had success with the pressure washer on the cheap and thin liners and with the so called good quality liners ( rhino, line-x, etc... ) lol, the cut and pull method as work. If its stuck pretty good you just have to grind it out or at least most of it and then spray over it. Next time find a professional to do the work a least it would be warranty. Live close to Northeast Georgia checkout Css Innovations for a Speedliner bedliner price is right quality is bar none and you want be disappointed, and won't have this problem again.
