Allow me to clarify a few things.
PPG's product has been out for years (I think since 2006). It is the Nissan "factory" bedliner and now it's being applied to SOME of the Ford F-250's (only). Miltough is NOT the bedliner product they are putting in these trucks, the product is called PPG Durabed.
LINE-X PAXCON is being applied to military Humvees, MRAPS produced by Force Protection, U.S. submarines, and PAXCON has been applied to portions of the U.S. Pentagon. LINE-X was the first to produce such a product. Rhino and now PPG have copied it to a certain degree. LINE-X XS-100 (used for bedliners) has been used to coat military bullet proof plates (worn on chest and back).
The do-it-yourself products have their place, but they are not as durable as professional products. Actually, they are not even close.
