I have been recommended to
- wire brush most of the rust off
- use Kurust on what's left
- cover it all in waxoyl

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.

Quite. Additionally, whilst they can be very efficient, the 'risk'
(for me anyway and including the wire 'bullets' that have gone though
several layers of clothing) outweighs the advantages.

But then I have watched (then later felt) one catch the ground, fly
into my knee and after going though my jeans, push all the skin up to
one end of the slot ... then after about 30 seconds, start to leak
profusely. ;-(
