The video you saw may have been mine.

I recently finished treating a seam. (my first time doing this job)
The caulking had failed, water just "poured" with a water hose to the
seam. As an aside, this area of the van appears to have been
"professionally" repaired. In hindsight, I suspect the caulking
material was either the wrong stuff, or poorly applied. I don't see
signs of seam failure elsewhere.

Though there was no visible signs of rust inside or out, once I ran a
piece of thin emery paper along lower portion of seam, I could see
signs of rust on the paper.

I guess my point is this; even with what appeared to be a rust free
seam, I ended up finding signs of rust.

FWIW, after cleaning and prepping the seam, I used a syringe with a
piece of electrical shrink wrap attached (as a nozzle) to inject rust
convertor as deeply as possible into the seam, then painted, caulked
etc. I used Proform 211

 though it was a little tricky to shape.
