A minimum 12 mil DFT (dry film thickness) is recommended for marine applications. Additional coats or mils may be needed for adequate protection dependent upon substrate and exposures. Sea temperatures vary, as does the salt content; these factors may also help determine the appropriate DFT.

Rust Bullet is formulated to provide excellent corrosion resistance, even in harsh marine environments. The coating forms a tough, durable barrier that protects the underlying metal from the corrosive effects of saltwater. When properly applied, Rust Bullet adheres strongly to the substrate and maintains its protective properties over time. It is designed to withstand the physical and chemical stresses associated with marine environments, including constant exposure to saltwater.

Refer to ASTM B117 Seawater Spray (Fog) Test Results and ASTM D870 Seawater Immersion Resistance Test Results for further technical and engineering data on saltwater exposures.
