Put on a protective face mask and a pair of gloves. Open a window for ventilation, or spray paint outside. Cover your work surface with a drop cloth or newspapers.
Scrub the metal with a wire-bristled brush. Wipe away dust with a damp cloth. Let the object air dry.
Apply a spray primer made for metal surfaces to the object. Shake the can well, and apply by depressing the nozzle and moving the can back and forth about 10 inches from the surface. Let the primer dry for one hour.
Shake the can of spray paint for two minutes to thoroughly combine the pigments and the paint medium.
Depress the nozzle of the spray can, and apply the paint in a thin coat using a smooth, continuous motion. Keep the nozzle 10 to 12 inches from the object. Let the paint dry for three hours.
Apply a second coat just like the first. Let the object dry for three hours before moving or using it.
