Painting rusted beams

On my outdoor kitchen I have a lean-to that uses something like iron as the frame. These beings were never treated or paint it so they are Rusty. It is 100% covered in what appears to be rust. My question is can I paint this and what would be the pros and cons of painting? I'd simply like it to be painted white so that it matches everything else on my property.

Got a picture?
Most often it's wire brushed, primed with gray rusty metal primer then painted.
Rustolium works for me.

If the rust is really heavy and flaky then you will probably need to do some sanding/wire brush to remove.

If it's light rust then a coat of rusty metal primer and paint will be good.

If you want to go one step more, get some rust converter, treat the rust and then primer and paint.

Rustoleum or Krylon are decent DIY products.

You always want to remove as much rust as feasible! Both the primer and top coats need to be oil base.
