Since theres no line X I would go with Rhino, due to national warranty alone.. Ive had the rhino and its not bad (97 s-10). watch for drips and make sure they spray it on thick enough.. The rhino is rubbery so it may scrap off if you drag a sharp object across. none the less you have a national warranty. Ive also had lava and its not good at all (00 s-10).. no opinion on pamalu.. you could always ship the truck to the big island where theres a line x dealer there! just kidding.. I currenty have the line x on my tundra here in CO and its superior IMO but if I were at home, Id do rhino. dont forget to wheel and deal..if your going to the one close to sand island they are pretty good. good luck.. oh if you want to be really safe buy a used bedliner and stick it in the bed once the spray
liner is done, that way youll have double protection. the bed will still dent if you have rhino.. I put in, well threw in a few hollow tile blocks and it did dent the metal in my s-10 so now i have line x and a hard
liner, its the best defense yet..
