I believe there originally was one about 4 inches back from the front, and
another about 2 inches forward of the back of the sill. If not, I'd sure
put holes there. I put approx 1/2 inch holes, used them to inject waxoyl,
and left them open.

I think the problem is less water than the dirt and debris these collect.
I drilled a couple of 3/4 inch holes inside (later covered by the inside
panel) and waxoyled the heck out of these box sections. I plan to pull
the inside trim panels off, and using a bent 1/2 inch copper water pipe
sleeved into a vacuum cleaner, either suck or blow the debris out every
couple of years. I did not think of cutting a hole through into the
rocker, but I suspect that would just let debris into the rocker, which is
harder to replace than the A posts. Anyway, we are probably taking a lot
better care of these cars than they originally got. I don't figure mine
will rust out in my life time if I continue to care for it as I do now.

I doubt if painting helps much, but it doesn't hurt so I do it. I have
tried weld-through paints, but they are not weld through in my hands. My
answer was to pick places for 1/2 inch access holes while everything was
apart, and to waxoyl the cavities with a high pressure undercoating gun.
