RUST in the ROCKER PANEL?

I am going to have a rust repair/restoration/new paint party once mine is out West and away from the rust belt .

I found the same rocker rust when I did the LineX job. I just filled the rear fenders with expanding foam after removing the cancer portions. Then, shave the foam down even with the metal, LineX over that, never worry again
I am POR15ing the frame as well. Not terribly worried about the frame as it was all surface stuff. I did the axles a few years ago, just bought a cheap HF baking soda blaster and then primered, POR15 the housings. A lot of labor, but nothing terribly difficult to do.
