Can the Rust-Oleum Stops Rust, Crystal Clear Enamel, be applied on top of Rust-Oleum "Professional High Performance Enamel?

Great question, thank you for reaching out! Yes, our Rust-Oleum Stops Rust Crystal Clear Enamel Spray may be applied over our Professional High-Performance Enamels. To prevent surface reactions such as wrinkling, it is important to follow the specified recoat times printed on the product labels. With these two coatings, the clear coat may be applied up to one hour after the High-Performance Enamel. If the previous coating has dried for longer than one hour, we recommend allowing it to dry for at least 48 hours prior to applying the clear coat. - Rust-Oleum Product Support 2
