Metal ShieldRust Prevention Coating & Anti-Corrosion Metal Protection
- Rust Prevention Coating - stops corrosion, oxidation and galvanic deterioration on all metal substrates
- Clear Rust Inhibitor - maintains natural metal appearance without film buildup or discoloration
- Anti-Corrosion Defense - resists salt spray, acid rain, UV degradation and moisture penetration
- 5-Year Limited Manufacturers Warranty
Overview
Metal Shield is a clear nano-coating that prevents rust, salt spray damage, and galvanic corrosion on steel, aluminum, copper alloys, and stainless steel. It delivers 2,600 PSI adhesion and carries a 5-Year Limited Manufacturers Warranty.
Corrosion costs U.S. industries over $276 billion annually (per NACE). Metal Shield eliminates this liability with a nano-coating barrier that prevents rust, salt spray damage, and galvanic corrosion before it starts.
The clear formula preserves the appearance of architectural metalwork and structural steel while providing long-term adhesion on steel prepared to SSPC-SP6 commercial blast standards.

Frequently asked questions
FlameOFF® Metal Shield is a single-component solvent system, meaning it does not require mixing two parts like traditional epoxies, allowing for faster application. Unlike most epoxies, which are not UV stable and can yellow or degrade in sunlight, Metal Shield is UV stable and performs well outdoors. Additionally, it creates a covalent bond with the substrate for superior adhesion.
Yes, it is a high-gloss clear coating.
Yes, the product is UV stable and performs well both indoors and outdoors. Accelerated UV testing (ASTM G154, 1000 hours) shows minimal change (dE < 0.5).
Durability depends on usage and exposure (coastal/inland, chemicals, salt, abrasion). It comes with a 5-year warranty under recommended applications, but will perform longer under many conditions.
Yes. The coating can help revive faded pigment and improve the surface appearance.
No. Due to its solvent base, it may not work well with 1K paints like alkyds, latex, and acrylics (potential for hairline cracks). Always conduct a compatibility test first.
Yes, it can be used as a protective topcoat over industrial 2K paints and epoxy paints. This can help reduce the amount of expensive epoxy needed while providing a high-gloss, chemical-resistant finish. Always perform a small test in a discrete area to ensure an acceptable finish before widespread application.
Absolutely. It creates a non-permeable barrier that shields against moisture intrusion to prevent rust.
No, it is not recommended for car body paint as it requires professional application and is difficult to remove. However, it is excellent for protecting undercarriages and frames in salt-corrosive areas.
Yes, it is highly chemical resistant. It can withstand petrochemicals and strong acids, including 87% sulfuric acid for 5,000 hours without change.
Apply to a clean, dry surface using a commercial-grade HVLP (1.0-1.3 tip). It can also be applied via brush, roller, or dipping.
