Painter John Dee from the television show "This Old House" points out that surface prep and proper priming are just as important as choosing a quality paint. In his online Q&A "Repainting Metal Railings," he recommends cleaning the metal surface with a wire brush, then scuffing the existing finish with sandpaper for better adhesion. Wipe down the surface, then apply a rust-inhibitor to bare metal and rust spots before priming. Dee advises to use spray paint instead of brush-on for a smooth, even finish.
