64 SWB tailgate openings

I have repaired my 64 tailgate. Cut out and welded in several pieces across the upper and lower horizontal pieces. Why do these corrode from the inside out? I notice the gap-s on the end uprights and wonder should those gaps be filled with seam sealer to stop some of the water entry into the upper and lower horizontal pieces. Anybody tried it?

You can seal the seams up, but don't forget to drill several 1/4" holes in the bottom, the pockets and sides where water can collect to let the moisture out. I did that, then thinned out some POR15 and poured it inside the tailgate, sloshed it around, and drained the excess.
