Default question about hidden areas of reproduction parts

So in the build of my project (1964.5), I have determined that the floor supports will need to be replaced as they are very badly rusted. I have a pair from CJ Pony Parts that came painted black.

After repairing (replacing) a bunch of stuff, the car will be blasted and epoxy primed. My question in this: once the floor supports and floor pan are replaced, the inner part of the floor support will be hidden and not touched by the blast/prime process. How should this area of these reproduction parts be handled?

I have been researching and can't seem to find consistent opinions on this matter. I have found the following suggestions:
1) Leave the black paint as-is and that it will be a fine corrosion resistor in these types of places
2) Epoxy prime over the paint prior to install of the floor pan
3) Sand the paint and then epoxy prime prior to the install of the floor pan.


Thanks in advance

my 2 cents:
If you are in corrosion prone location (geographically), I would advise at least priming the underside with an adequate corrosion inhibitor primer and use weld primer at the connection points. If you are not, leave the underside alone but still use the weld primer at the interface.
