Coastal Hawaiʻi is the harshest corrosion environment in the United States. Salt aerosol, persistent humidity, and warm temperatures accelerate steel oxidation orders of magnitude faster than inland climates. Without a serious coating system, exposed metal is a constant maintenance liability.
Rust Grip® is a one-part, moisture-cured polyurethane that bonds to existing rust rather than requiring sandblasting to bare metal. The chemistry encapsulates the rust, stops oxygen and water from continuing the reaction underneath, and locks in 6,780 psi tensile strength to the substrate.
A single coat replaces the traditional sandblast-plus-three-coat system. That’s the labor-cost story.

The Wet Surface Specialist
For surfaces that can’t be dried — boat hulls below the waterline, water tanks, subsea pipe — Moist Metal Grip is the right choice. It’s a two-part epoxy that bonds to wet, damp, or fully submerged metal, with potable-water and AWWA approvals.
