Can anyone recommend (through personal use and not hearsay/web hype) a
good rust killer plus primer to use on a small awkwardly located rust

it.

The top coat will be a silver grey metallic fwiw.

If you can clean it fairly well (70% bare metal) it's hard IME to beat
red oxide primer. Them work up as you wish with other paints.

Years of my father battling a crappy rustbucket Fiat when I was a kid
taught me none on the magic remedies work, with the possible exception
of phosphoric acid which almost seemed to do some good. Jenolite was
crap. Zinc preparations were useless.

That's strange because Jenolite is basically phosphoric acid. I
have found the red Jenolite liquid (not gel) to be very effective
but only after removing loose rust I.e. to prepare a surface with
traces of rust.
