What color is it? I'm assuming black, but I came across a lot of orange
bubbly not-too-flexible-any-more type of stuff in many joints. I'm pretty
sure it was reddish-orange, and was also under the (original) signal red
paint.

Was it used for every single join (spot-weld...?) or just the ones the end
user would see?

The inside of the trunk of our 83 Oldsmobile seems to have a sort of
plasticy compound. I don't know where I can get it- but I bet I could
find out next time I'm near a body shop / paint store.

I've used roof patch compound, which is about the consistency of
toothpaste (though not as tasty), and has a lot of asphalt and fibrous
stuff in it. It works well as a temporary measure, for holes that I don't
want to fix, I also swim a bit of zinc stripping (also used on roofs, to
eliminate moss), cut to fit, and glued in.
It hardens in a month or more. It does seem to get a bit brittle, but
only if you use far too much- I try to keep it thin and out of the
weather- and haven't had any trouble now.
FWIW it also seems to take paint, but I will have to wait and see if
there's any cracking or bleed-through or other nasties.
