Hi Dave,
I had Reflex brand bed liner sprayed in the 61 Ford once I got it home and cleaned out. The Reflex stuff is really rubbery, about like tire rubber, or slightly softer, but a tad harder than an inner tube. They can put it on as thin or thick as you want.
I used that brand because they are local, I know the owner, and they did my Dad's truck bed. He said it would help lots with the sound. In the end it was OK, but not worth the effort if sound deadening was the only goal. It did smell pretty bad for about 2 or 3 days, I was not warned or expecting that, and a day after it was sprayed I drove to the Colorado show, even with the windows open it was a little strong. Smell went away all together in about a week.
I am sure the Reflex brand stuff would be good for a flexible removable floor mat, about 1/4" thick would be good.
Just recently I had the end of my fuel tank coated with Line-X, and inquired about having my cab floor and under my fenders and cab coated. They had a sample and it was really hard, almost like Masonite, not rubbery at all.
I also told them about my less than satisfying results with the Reflex brand stuff used on the cab floor for sound deadening. The Line-X folks explained it to me, and I forget all the details, but something about more of one ingredient in their stuff and less in the Reflex brand. They say that Line-X will do a far superior job of sound deadening than Reflex, and they regularly get vehicles in to coat the inside just for that purpose.
Line-X did not smell at all even an hour after it was done, I had the fuel tank in the back seat of the truck for the 3 hour ride home, no smell.
So, Reflex brand may be great for a removable floor mat, and Line-X may be best for a permanent coating and sound deadening.

Thanks, I'm headed out to work on it now, may have it running before long.
