They sell a product called CORROLESS RUST STABILIZER.
I've used this product in some muscle car restoration
projects as well as some tower/hardware repairs. This
stuff is simply painted or sprayed on the affected
rust area. It can then be painted over or left "as
is". I've never seen anything I've treated show any
signs of rusting again, even years later. This is the
same stuff developed and used on offshore oil rigs.
It's available in brush-on form or also in spray cans.
