I had Rhino spray the bed (and top of the bed rails) of my Ranger in '95. The most it carries is dirt bikes, ATVs and associated gear, plus it spends most of the time sheltered in the garage. However, I still think it's the way to go. I watched them spray it on. At that time, prep work changed from the time I had my uncle's Dakota Rhino'ed a couple years before. At that time, they did do the bed grind. For my truck, it was some sort of chemical application of a bonding agent. My uncle's truck is a ranch truck so it gets lots of abuse, yet it's held up well in nearly 10 years. Only one small tear. In both trucks, the sun seems to have faded the black color a bit, but I hear that Rhino does have a color renewal agent available now. No big deal to me so I haven't investigated further. However, I'd go Rhino again without hesitation. [:)]
