My father and I recently began a buildout of a Ford E-350 Shuttle Bus that is currently being called the "BumbleBus". He recommended leaving the original flooring(rubber top, plywood underneath) and build new floor on top of that HOWEVER I couldn't turn a blind eye to what's underneath. And I'm impulsive..
After pulling up the rubber I got to the plywood which was 2 layers on top of the base metal. I have 2 questions and was hoping someone, anyone can help:
1. Should I remove the layers of plywood to get to the base metal?(rust?) I'm in the process of removing those "metal floor things"(in pic). Each one fit snug in the top layer of plywood and drilled through the next layer of plywood and base metal all the way to the outside(will need to be sealed). Would be easiest to sand the ply however I don't mind removing the ply if I have to.
2. Instead of using the plastic casings that fit on top of the tire casings(as seen in photos) can I apply something to the metal that serves as a more attractive temperature barrier? This would be post getting rid of the rust.
Thanks to all who read. Looking forward to journey.
P.S. I'm a NOOB at pictures. I'll update soon so they're not sideways
