I learned or should I say that I surmised, during my repair that the hole in the jack support is there to drain water. But what it does is let dirt and water in. Once the dirt is in and packed, the water is absorbed and starts the rust process from the inside.
So it should be on the maintenance list to take a punch and break up the dirt in the jack support once a year. You have either eliminated the access point for the dirt and water, or eliminated a way to get it out by welding a solid plate.
And maybe should drill a hole in your new plate and force the "rust mort" in there. Cause the rust was on the long side too.
I did a similar repair, but left the hole and used a similar product to rust mort. An inner channel spray paint from Eastman on the inside.
(EDIT) I just realized that in your photo, you can barely see the hole I mentioned. It is on the bottom left of the "pyramid". This photo may be an item that will work on either side. Hole on the top too.

I did leave out a few pictures
That is probably why some folks are making negative statements
Sequence of repair:
1 Grind off all rust
2 Treat inner and outer pyramid with rust stop
3 cut out rust
4 weld new plate in
5 cover with undercoating
This was the exact procedure I was going to follow.
The only additional steps I see:
1 Fog inside main long and inner long with Eastwood green rust stop
2 Spray Eastwood Rust arrestor on bottom of longs and a few sections under the car
I do not see the issue here
Thanks for the constructive responses
