Seam rust comes through from the INSIDE of the sills. If you can see
rust on the outside, it's BAD inside. And the ONLY way to get rid of
it is to cut it out and replace the cancerous metal. You can get rid
of the seams entirely in this way...

Commercial  rustproofing is nothing of the kind. It only delays the
problem, and makes any panel repairs very difficult because of its
tenacious greasiness. But I have talked to a motorcycle restorer who
tells me that rustproofing inevitably eventually flows down to pool
in the bottoms of open spaces, leaving most surfaces exposed to
resume rusting. His take on the matte: forget it. Do the job
properly, do it ONCE.

I'm happy to say that my outdoors-stored 84 has ZERO external rust.
