Recently I discovered rot hiding under paint right at the back of the RHS body sill in front of the rear wheel arch, and also part-way along roughly under the B-pillar area.
This is what it was like after I'd fully exposed the rear sill hole:

and this was the same location after rust-converter treatment prior to filler:

This is the decay under the B-pillar area after treatment - note how it looks like the metal is really thin almost like the steel has decayed from the inside to become almost like 'steel foil'...

I've done the best I can do with treating and filling the decay areas, but the amount of rust I could see *inside* that big hole in front of the RHS rear wheel bothers me and it's one of those body cavity spaces that are basically impossible to see into without something like a telescopic inspection camera (that I don't have).
I am thinking I will find the same thing going on with the matching area at the rear of the LHS body sill but haven't investigated that side as yet.
Now my questions are - how can this be inspected from the inside and how can it be treated from the inside if there's anything that can be done. I have no idea how the rot has occured.
Anyone else dealt with this in their 80? I know there are problems with body rot in the front where the firewall panel joins to the front half of the bottom floor panel, but didn't expect to get rot at the rear of the main body sills.
If that bung was taken out it's pretty close to the site but still wouldn't be easy to see inside without a fancy inspection camera gadget.
This is the RHS body sill after I've shaped the filler as best as I can and primed it ready for a final paint coat:

Is something like Killrust Fishoilene suitable to use inside sills, etc. where access is extremely limited as a way of keeping a lid on the spread of rust?
Another product I've come across is Eastwood internal frame coating.
Short of commiting to somewhat major surgery to wholesale cut out and repair the body sills, what other approaches are worth trying to see if I can slow down the progression of the rust inside the sills and any other similar enclosed and very difficult to access body cavity spaces?
