See my post from Pirate........

the heavy rust through is from brackets or nooks and crannies that hold mud, dirt, etc.

when it gets moist the rust demons wake up and go to work.

the waxoyl thing really does work.!

I frankly don't know, But I have the same issue on the driver's side of one of my cruisers. Would sure like to prevent it from happening. Post up people.

On my 73 on the drivers side, I have 3-4 conspicuous rust holes at the top of the rocker which bleed rust stains down the outside of my rocker, like in your photo. My guess on this is my early style door has a rubber gizmo flapper seal on the outside of the window glass...that some time ago turned to shiite. It then allowed dubious amounts of water down the inside of the door panel down to the drain holes which collect mud, crap, etc., mentioned above and this toxic goo "worked" on the top of the rockers in those locations. I'm not sure about your big hole just ahead of your rocker...

The rust hole is on the back side of the door post. The outer body skin is spot welded to the door post which make an area where the sheet metal is doubled up. Any water that gets between the 2 sheets will rust and push the 2 panels apart till it rusts though. The outer skin is the thiner of the 2 so it pushes out. Even with the body being sealed at the factory the door post has enough movment with the hinges and door stops to crack the seam seal and let the water in. Mine had a crack in weld at the bottom of the door post just in front of the seam for the rocker panel and thats where the water got in.
