Bull Frog Rust Blocker Shield

Bull Frog vapor corrosion inhibitors (VCIs) are water-based non-polluting molecular coatings that protect metals in enclosed spaces for a year or more at a time. As the VCIs migrate through the surrounding spaces, they bond electrochemically to metal surfaces, providing an invisible Molecular Umbrella of electrochemical inhibitors that seal metals against the air and moisture that cause rust and corrosion. They protect any metal surface that air can reach, and they leave no build-up of oil or wax, nothing to contaminate your hands or work. The 10" x 10" shield protects for up to 50 cubic feet.
