I used "herculiner" on my F250,its similar to the rhino liner. The stuff is great!! I performed a diy installation with a brush and roller. The finished material thickness is about 1/8". It is apparently realy rugged stuff. Ive seen a truck with a rhino liner bed I think its great stuff also..

The problem with the plastic drop in bed liners is water gets trapped under them, they shift and wear through the paint, and the bed rusts through eventually ( the only rust on my 200,000+ mile Toyata p/u was under the bed liner)

Bill the rhinoliner and herculiner are spray or brush on applications. From what I have read they are vinyl paints withrubber particles suspended in them. I doubt water could penetrate through 1/8-3/16" of the stuff.

BTW herculiner is made in NZ
