repainting window lintel

I need to repaint the steel window lintels of my windows. They are peeling badly. I am just wondering what is the best way to prep them before I paint? Thanks

Also, if I use a rust paint after prepping, do I need to prime first?

Instead of using paint, I would highly recommend stripping, cleaning, and cold galvanizing them.

By cold galvanizing, do you mean spraying a galvanizing compound on like the one below?

Yes, there are several kinds... all are high in zinc, which bonds better to steel than ordinary paint.

Most of the lintels I've painted I just cleaned them up [remover rust, flaky paint] applied a coat of oil base primer and then a coat of an oil base finish paint.

I do agree that zinc based coatings are superior for steel.
