Few primers are really water proof. Rustoleum used to have a fish oil
base, maybe still does. It sticks pretty well. I have seen auto enamel
painted over rustoleum primer; the trick is to give it several weeks to
dry. I don't think primer alone will provide protection, though. You
would have to put some sort of finish coat over it to seal it.

Never heard of it.
If it were mine and worth much, I would bite the bullet and have it fixed
now by a body shop. If finances dictate that you wait, or if it is pretty
battered now, then rustoleum red primer followed per instructions by
whatever rustoleum top coat is closest to your truck color should hold it
for a while. If you decide to have a real paint job, it would be best to
have them remove this paint and the rust.
