JB weld pits in floor pan?

Hey everyone, my passenger front floor pan has one section that I need to cut out and replace, but it’s also has some heavy pitting here and there with some small pin holes. Everything around the pin holes is really solid and I’d like to not have to cut out the whole pan and replace it if I don’t need to. So, should I try to fill the pin holes with my flux core welder or should I just put a skim of jb weld over all the pits?
Here’s the floor after I wire wheeled it, obviously that top right corner needs patched.

And here’s with a light under the pan to show the pin holes. As I said, the pan itself is surprisingly solid.
