Nice work,
You got the right idea tons of small steps. The foam is a huge pain, just from amount of physical labor to get it out! The white hard globs on top of the stringers is not 5200. It’s some type thickened epoxy, wellcraft used as glue. I used a sledge hammer to knock it off where I needed to take measurements and get levels. I didn’t bother with most of it since I was cut out the stringers anyways.
Once you get the foam out you can get a real good idea of how much needs to be replaced!
