Ive used rhino liner in all of my trucks, and i havnt been disappointed. it holds its own against graval, rocks, logs, ford engines haha (zing) not too sure about the line ex, but ive heard good things about it as well. haha i think you can get rhino liner with kevlar now. i wonder what thatd be like. i hope i was helpful in some way. gluck with the linin. FYI, dont get it on your hands then pick your nose. dear god man, it pulls all the little hairs out haha.
