Have you decided what you are going to put on top of the epoxy on the bottom of the cab?
I used this stuff for Korbin's truck We like the way it turned out. It is availabe in Black and Tintable. We used the Tintable so it is the same color as the truck. The black probably covers better, we sued a whole kit for the bottom of his cab. Not bad, found it online for $121 shipped to our door.
