Rust-Oleum Stops Rust Protective Enamel with Custom Spray 5-in-1 technology provides a premium spray paint experience with unlimited ways to get your project done right. The innovative Custom Spray 5-in-1 dial allows you to choose from 5 spray paint nozzles for ultimate control and the advanced Stops Rust formula provides 30% greater corrosion resistance and color retention compared to the standard Stops Rust formula. Use the high output spray nozzle for large curved surfaces, standard for a traditional experience, low output for details and corners without drips and runs, and vertical or horizontal fans for flat surfaces. When you're done, turn the dial to the locked position and store the remaining spray paint for your next project.
