We recently purchased a 2013 Sierra with this Rugged Liner bed liner installed. It is the type that fits over the bed rails and is secured to the truck with 4 fastener clips. Apparently the thing moves around in the wind as it took the paint off the top of the bed rails at each end.
We're going to do paint correction and then cover the rails with the GM Accessory covers like the ones on the white Sierra. With clear skies we went after those fastener clips and had to break each one to remove the bed liner from the truck. Once done, it was obvious that it had not been removed in years, probably since at least 2015. There was a ton of Oklahoma dirt and leaves underneath. Once cleaned out the it was apparent that the liner had wore away the paint across the entire bed. The GM liner in the white Sierra has not done this. If the previous owners had done nothing, the paint would be in better condition. The bed and liner appear as if nothing was ever hauled back there, not a scratch in the plastic. Arghhh!
My daughter is washing the truck right now and I'll post up some photos of the paint later.
It's later:

Anyone else experience this? Any recommendations on paint correcting these areas? I purchased an ACDelco paint pen and rattle can and also have clear on hand in rattle cans.
