I have been recommended to

Any other / better suggestions?

Depending on the level of 'rust' and how 'stripped' the trailer is,
use a flapdisk thing (in an angle grinder), along with a wire brush
(had / drill) to take it back to bare metal and re-paint with a decent
red / grey oxide type primer and a couple of coats of a chassis paint
(or Hammerite if you have some to use up).

I prefer a twisted-wire cup-brush in an angle grinder. Good protective
clothing definitely needed though as wires come off at some speed when
they let go.

A wire disc in an angel grinder gives the greatest linear speed & thus rust removing ability & speed. Cup brush comes 2nd.

OP options are to grease it somehow (oil, oil & wax or brand products) or strip & paint, or both.
