Oil-based paints are the most durable. You’ll achieve a more uniform finish if you first apply an oil-based primer (e.g., Rust-Oleum Clean Metal Primer , $8.98 per quart on Amazon). However, you can apply oil paint directly to metal because it contains no water, and therefore there’s so no risk of rust.
Applying paint in thin/light coats (three coats preferably) will guarantee the best finish and protection on your metal . A good top coat will give your painting job more reliable and durable protection and also a final polished shiny look. Apply topcoat with a good quality brush or spray on it.
To properly prepare new metal surfaces, use mineral spirits to remove grease and apply a rust-inhibitive primer before painting . For painted surfaces that are in sound condition, remove dust with a clean, dry cloth, de-gloss the surface with light sanding, and wipe with mineral spirits to ensure good adhesion.
Use a brush or roller, or use a spray paint formulated for application on metal (manufacturers like Rust-Oleum and Krylon offer “all surface” spray paint in numerous colors and sheens). Apply several light coats, letting the paint dry for a few hours between coats.
Spray painting is faster than brush painting . Most spray paint is oil-based and provides a more durable finish than latex paint . Spray paint can be used on practically any surface, including wood, metal , wicker, plastic and resin. Spray paint dries much more quickly than brushed-on paint .
While metal paint primer is not always a requirement, it is always recommended, especially if the metal will come into any contact with moisture. Untreated metal requires primer to seal it from exposure before any topical paint may be applied.

The best paint choices for metal surfaces are Oil or Enamel based Paints. Oil -based paints and metal surfaces go together like crab and dumpling. They are usually the best option for metal surfaces. Sure latex paints can work however, they are nothing compared to oil or enamel based paints for metal surface types.
