spray on bedliner? ask and ye shall receive
there are 2 different kinds
"undercoat" is half the price, and half the texture
this is behind the interior panels of my old truck

i didn't really do much prep, i just wanted a little extra sound deadening. notice the smooth texture
now, heres the "truck bed coating"

its coarser to the touch, and the color looks more "dull" than the undercoat (which looks more "glossy")
you can also use it to give a little more "pep" to your interior panels (mine were very scuffed/scratched in this area)
prep work is key! i didn't do much, this was just an experiment to see if i could save a few bucks by not buying the roll-on. for my use (offroad/fishing/camping truck,) i would have been better off using the roll-on, its a lot thicker and more durable.
btw, if you are looking for a way to "clean up" the bolts on top, use carriage bolts (the ones with the smooth dome top). they look like they need a square hole to seat properly, but thats only if you are using a lot of torque. with a round hole, you can just hold the top by hand and tighten the nut underneath.
i like this idea, makes me wonder if it would make a difference on my suv. i know theres a major low pressure area back there, its enough to suck dirt past the rear hatch seals.
