I put Herculiner on a used bed slide I refurbished. Was very happy with the results. I had Rino in my 2000 and it held up well the 16 years I had that truck. My 2016 had an aftermarket spray in from a shop that did it for the local dealers. It held up well the 7 years I had that truck. My 2023 has a spray in liner, I assume from Ford. All my trucks had caps so no sunlight worries.
