Is it normal for the factory bed liner to start turning a faded black color? Also is there any tipe of cleaner for it that would restore its natural look? Thanx!

Spray in or drop in? If its spray then there is a TSB for it.

It is a spray in liner, part of the utility track package.

Print this TSB and call your dealer. I had mine redone. In the process, they found the dreaded liner bubbling issue. Waiting on the local Linex company to get trained by PPG to fix it. That's my dealer's story anyway.

Thanx LDO, that was some good info. I am looking into it as we speak.
