Paint for outside table

[boyse7en]

I've got a round metal garden table that needs a refresh. What type of paint can I use on it for a nice durable finish? Planning on roller of brush application.
It's a smooth flat metal table top, so I don't want a textured finish like Hammerite, just a nice gloss or satin finish.

My normal go to would be anything by Zinsser. All coat I’ve used on a garage door and it lasted ok given a poor undercoat / existing surface and it being in full sun all day.
