Veronica, if you want a fast fix, you can spray it with any kind of outdoor spray paint, Rustoleum comes to mind. If you want to brush it on, then you'll have to use an outdoor enamel. I'm pretty sure you can get it in latex now, too, not just oil/enamel. Look to see if it says for outdoor lawn furniture or if it's ok to use on metal. Acrylic paints that you brush on will probably peel right off after drying. Metal usually resists it.
