Had Linex in my last truck. It was OK but over a few years looked old. And sliding was a problem. This truck I did no coating. But went with a heavy duty rubber bed mat. No sliding. Fits under the rails for my SuperGlide nicely. And when I installed it, I slit it on 3 sides to make flaps, around each SG mounting pin. And when the hitch is in the bed, just fold up the flaps to allow the pins to come through it. When the hitch is out, the flaps close down and there is virtually no evidence the hitch was ever in the bed. And when hauling dirt the bed mat cleans up nicely.
Of course I do not use a truck bed very hard any more.
