I knew a guy who used stuff he bought in 1 gallon cans at Home Depot.. you had to roll it on, and the stuff was thick as tar.
When it hardened, you could transport molten lava in the back and not hurt the coating.. when he sold the truck 2 years later, it looked as good as the day it went on.
Another friend used the same stuff to coat the floor and walls of his cargo van with equally impressive results.
I plan on using the same stuff for the cab floor of both my '46 trucks.
