I've recently replaced the one 6m length of PVC gutter bodge on the
house with cast iron to match everything else (a slightly tough job,
single handed; where are the off-spring when you need them?) The new
stuff was pre-painted and looks great, but it's reminded me how bad the
rest of the guttering looks (in good condition, but bad paint and with
leaking joints). The plan is to take it down in sections, wire brush,
paint, re-fit with new bolts and seals, and to adjust the brackets to
improve the falls. The question is what to paint it with.
My first thought was inside and outside with Hammerite smooth, but I've
read reviews saying that it flakes quickly and is a pain to apply ("not
as good as it used to be" is a common comment). Other suggestions are to
use bitumen paint inside and almost anything outside.
Any recommendations from people who have relevant experience?

A while ago I needed to paint a metal framed A-sign for outdoor use. I used:

Zinsser All Coat Exterior Paint Black 1Ltr (Screwfix 8716G)

Was really nice to use - wash brushes in water. Quick drying.

Unfortunately, it is quite expensive and I don't really know how well it lasts in the longer term.

Thanks. It gets good reviews.
