Putting (expensive) paint on sills that will just bubble from inside, is a waste of money; everybody would agree I think.
If however the internals are solid, then I understand a choice to have it blinged-up and drive it for 10 years.
Problem is, I wouldn't know what you have in your hands.
So in order to make a solid choice, I would want to have a clear list of pro's (what's still solid) and con's (what's rotten).
You can only get that view by taking every bit of paint and bondo off the rockers, to get a better look at what's below.
Just cleaning the rockers is just a 2 hour job but its messy. To bondo it back up is no big effort, partly it is needed already. Also its covered by the decorative trim panel anyway, so it doesn't need to be mirror finished. Ask for bare metal from wheel to wheel, for 5 inches from the bottom upwards. Left and right.
Then pay them a visit and talk. I'd guess that you will find some holes.
I would always take the next step; Where ever there is a rust through hole, ask that it is opened up to check the layer below. If you again see holes, dig deeper...
If there are worms, find them or they'll simply eat their way out again.
It can turn out as a lot of work, or you could be surprised by marginal brown deposits.
Doing it this way provides massive insight and the right grounds to make a choice.
As a figure of speech; the further down, the worse they get. Don't think it'll be better closer to the ground.
See enclosed 2 images from your video.
Right rear quarter: I for one have doubts about these dark spots, which I think are holes through your outer sill. (inside the red square) If they are indeed holes, the intermediate sill will have rust too. Mind you there are three more layers in places behind it;
Left rear quarter: it's a guess but I think the lower portion of the B-pillar is gone, based on the rust that is visible it he orange circle. Where your body guy starts peeling bits off, you can see the transition of the inner sill to the lower b-Pillar. behind and below it gets even worse; i'm sure. behind the red circle I think it will be better, as that is a more closed area. I included a pic ("lower b-pillar left side)" of that exact spot on my car for reference; with the intermediate sill partly stripped out (it was wafer thin, just a pair of pliers allowed you to shred it to pieces). The bit of your B-pillar in the green square looks worse compared to that bit on my car...
Facts, not hopes, make better choices.
Another hot spot: How is the floor near the subframe mounts? I tried to indicate their position in the left side photo with the red arrow pointing upwards. Look beyond the sill, and upward. There is a large cilindrical rubber bushing that holds the rear subframe to the carfloor. Quite usually the floor also shows holes there. attached one pic from my car of that location. Remember it's holding your rear wheels.....
For what it's worth; I think that the rust in your sills comparable as on my car. Take a look at my thread on here somewhere (Fixing that little rustspot) if you want to get visuals of what could be (is?) beneath.
I'm hoping to be of assistance with the advice to expose the rockers.
