TotalBoat Rust Primer converts rust and prepares metals to be primed and painted. Use it on new metal for superior paint adhesion. Its unique, phosphoric acid-based formula is thin for easy application and excellent coverage of over 500 sq ft per gallon. Use it on just about any metal in high moisture, high humidity environments. It's perfect for marine engines and trailers.

TotalBoat Rust Primer is incredibly easy to use: First, use a wire brush to remove accumulated dirt, grease, loose paint and large rust flakes. Then brush the primer on. The metal will turn black to indicate the chemical change. Let dry. Simply brush off any dried residue and the surface will be ready for primer.

Available in Quart and Gallon sizes.
