What BD said.
A friend who works at a local Truck accessories place has a Rhino. He is not satisfied with it. When our two trucks are parked side by side, the difference between our two beds is absolutely astounding. As BD said, the Rhino looks like someone sprayed black cottage cheese on the bed. My Line-X is consistent and level. His has chips gone and some "flaps" where something gouged the lining. His is dull and cloudy in places. Mine is still sparkly.
Line-X, infrared. That's the ticket!!
