Per a previous thread titled "spray on bedlining inside a jeep" here are some pictures you requested.
This is a 80 CJ-7. When this guy bought this jeep, he took the tub off and had a Line-X brand liner sprayed inside the tub, under the tub, and inside the engine compartment. Then took the tub to a body shop who made it look sharp and gave in new exterior paint. The entire tub is either new paint or Line-X now. His is very particular about his jeep, keeps it very well maintained, and is meticulous about it. He has 2 complaints about the Line-X liner, and those are that his master brake cylinder has been leaking a little and it has destroyed the Line-X where it contacted the oil. I was surprised at how it was turned to a very soft rubber and can easily be peeled away. The second complaint is that when dirt gets worked into the Line-X it is difficult to clean so that it looks like factory new again. He says that it takes a while to clean it back to that "new" look.
I was not sure how to show the liner well in a photo except for making it high-res, but I am also showing a smaller version of the same photo if you need it:
