Follow along below as I show how nicely the underside of the car cleaned up, and how I treated and sealed the inside of the floor.

You can see how nicely the underside cleaned up, that's all original red oxide primer over all original metal.

Here is the floors after the original carpet was removed.

After wire brushing the carpet pad and underlayment residue, I found some pin holes in the passenger side floor, and on the driver side under the seat.  The driver side will be ok for a very long time, but the passenger rear floor will need to be changed, particularly if this car will be kept outside.

The treatment I gave the floor was very thorough.  I treated the rust with a phosphoric acid prep followed by primer with ZeroRust.  Once metal starts rusting to the point that it gets pin holes all the way through it, it really needs to be replaced.  You can see from the pictures that there is still a lot of solid metal there, but expect that in the next 3-5 years the rust will eventually start bubbling again, at which time the floor will need to be repaired with a patch.  All I did was temporarily hold off the inevitable.

I then used 3M seam sealer to seal the pin holes in the floor, and also went back and seam sealed all of the panel seams.

The driver side front floor was in great shape, and only needed wirebrushing and was primered with Rustoleum and then seam sealed.
