I'm a LINE-X dealer. I offer you some facts about LINE-X and Rhino:
LINE-X and Rhino differ quite a bit. The biggest difference is that LINE-X contains polyurea and Rhino does not. Polyurea enhances the bedliner’s properties: 1. LINE-X's temperature tolerance is 250 degrees and Rhino's is 175. As the temperature of the bed approaches the temp tolerance, it loses its strength. 2. Polyurea keeps moisture out of the solution thus making a more dense and solid
liner. Less moisture also means better adhesion. 3. Polyurea also makes for a tougher
liner. The tear strength of LINE-X is 304 pounds per linear inch (pli). Rhino is 145 pli. 4. Polyurea sets up very fast, that's one reason why LINE-X goes on with heat and high pressure. LINE-X dries in about 4 seconds, so you get an even application throughout the bed. Rhino takes a minute or so to even gel, an hour or so to dry. Before it gels, gravity can pull the
liner from the top ridges in to the low valleys. Rhino’s Tuff Stuff goes on cold/low pressure and thus has that “cottage cheese” or “rain on the windshield” look. LINE-X’s high heat/high pressure system gives it a more consistently applied texture, it’s sort of like an orange peel. The dealer can vary the texture from smooth to very rough. 5. Polyurea makes the
liner more chemical resistant, especially to organic oils and solvents.
LINE-X offers a NATIONWIDE lifetime warranty. Rhino’s warranty is only with the dealer that sprayed it.
Buy whatever brand suits your needs. It's good to have choices.
