Best paint for cast parts?

[mrbig]

Hi all, I need to paint my steering box and master cylinder. Obviously both are cast so what’s the best paint and method please folks?

In the past I would have used hammerite but I’m told that it’s a bit poop these days.

Thanks

Cast what? Iron, steel, Aluminium?

[mrbig]

Good question… pretty sure they are iron.

Or would a brush on brake caliper paint work?

Etch primer first?

[colnerov]

Yes, that's fine, and yes, etch prime first.
