Stop in for a cup of coffee

If you look at the floor, that silver stuff is that chimney flashing I use for soundproofing. Love it on the floor take out the mats and hit it with a hose. Tell you what that stuff is durable been in the truck for 4? years and looks good still.
Always been afraid of anything stuck on the floor for when its time to fix the rust holes.
What goes over it in that truck - pebble finish vinyl?
