I havent done Rhino or Linex but I am planning on Linexing the bed and the hood with the hood being color coded. I was quoted at about 500$ for the bed and another $500 to do the hood in custom color.

I had the bed of my truck Rhino lined a few years ago and I also paid a bit extra to have them run the liner up over the lip of the bed and down the side about an inch. This covered up the spots where I commonly banged up the paint and let me get rid of my lousy plastic bolt-in bedliner which had sanded down the paint pretty badly (sand and off-roading vibration). I don't remember the overall cost, but it wasn't particularly cheap.

The lining has survived several years of Arizona sunlight. It's not as dark a black as it was, but it has held up well. It gets spots when I spill oil on it (difficult to clean), but a dust storm or running down a dirt road drys that up after a while :-).

The only thing I don't like is that the old plastic bedliner was so slippery that it was easy to slide heavy things in and out of the bed, while the new lining is more rubbery, which prevents stuff from sliding out unexpectedly but requires more work moving heavy stuff around.
