Lightbulb Use ceiling panels for floor?

Hello all! After pulling up my relatively rotten subfloor, I found these very thin sheets of metal screwed into the frame of the bus. They are flimsy AF. Once I unscrewed them and lifted them out, I can see down to the ground. This seems different than most busses that have a full metal floor? Iím in a shorty btw.
So, I was thinking of using the (not rusted) ceiling panels in place of these thinner metal sheets. I would cut them to size and screw them down in the same way these sheets were, but I think Iíll line the edges with butyl tape to keep road water out while driving. I will paint the unpainted side (which will be the side facing the ground) with ďCold galvanizing compound, zinc rich coatingď which is used to repair galvanize steel, sheet metal, and fences, itís supposed to be corrosion resistant. Itís a restoleum product, about 8 bucks/spray can at my hardware store. My question is
Has anyone done this before?
And do you think itís a good idea?
I could use the metal sheets that in there now, but ooowee are they rusted. And buying new galvanized metal is WAY ABOVE my price range. I just priced a small sheet at my hardware store at 3íx5í was nearly 50 bucks and Iíd need about 14. Yuck. I could opt for a cheaper metal? But I thought, wth, why not use whatís sitting in my bank yardÖ comments appreciated!

The cleaner metal should work. Never buy your supplies from a hardware store. Get your metal from a metal supplier, there's one in every large area. Reuse everything that you can.

Buying steel

Go to places like ryerson or gorgenson steel supply. Buy as much as you need at once. I think you will find considerably cheaper. There is a lot of mark up from middle men.

Some bigger dealers have the metal on a roll and shear to length. Talk to salesman about what you want. Donít get sheets so big you canít handle them.

Look into zinc spray, it is a kind of spray paint. do that bare steel then spray undercoating from underneath.

What you are describing is a normal floor for a shuttle kind of busses I have been around.
