Protecting a metal object from rust generally requires it to be sanded down to bare metal and then applying a rust protective coating. This not only kills the original look of the metal but makes a little thin than it was before. The Rust Reformer spray from Rust Oleum stops rust in its track and prevents it from spreading all over with just a single coat. No need to sand the surface, just spray this paint over the surface and it will stick to it completely and form a protective layer.
