Let's talk about this, Michael! To ensure full adhesion of Rust-Oleum Stops Rust Clear Enamel Spray, it is essential that bare metal is lightly sanded to create a surface profile. Please keep in mind, this coating will take at least 7 days to fully cure in ideal conditions. After this point, the coating has reached full hardness and adhesion. We recommend avoiding scratching or abrading the surface before that point.
