Re-Painting an old piece of decorative metal work attached to my front entrance.

I just wanted some feedback on the process I'm using to paint this decorative metal work. I wire brushed all the lose paint and rust off. I'm prepping it with a rust converter. I can see the old layers of paint and I believe one is latex. Anyway, I was going to use a good quality primer for rusted metal and oil based finish paint.
How dose that sound?

Latex paint tends to flex better on metal that's expanding and contracting with sun exposure, especially dark colors. Oil primer underneath is fine.

I read that somewhere but I always thought you should use oil based on metal. Thanks for the tip.

What type of metal? Oil base won't flex any but is best for both adhesion and rust prevention, latex is somewhat flexable and has good color retention but no rust preventative qualities.

It's cast iron welded to square hollow tube from about the 1950's. I was going to prime the metal really well with rust preventative primer so maybe that will compensate for the lack of rust preventative in the latex.

Igenerally stick with oilbase when painting cast iron. When painting cast iron with latex it's usually beneficial to apply 2 coats of oil base primer.
