The formulation for Bull Frog Heavy Duty Rust Blocker Gel was developed for use in industry, the military and NATO. This technology is now available in a convenient 16 oz. spray bottle.

The Heavy Duty Rust Blocker Gel uses Vapor Corrosion Inhibitor (VCI) technology to form an invisible electrochemical umbrella to seal metal against corrosion causing air and moisture. The VCIs in the gel migrate to seal the adjacent metal.

To use, just spray it on the entire surface to form a thin coating. The product will slowly dry to a thin clear film. This clear film will stay flexible so scratches in the surface will heal to continue to protect your metal from corrosion. This thin surface isn’t wax or oil based so it isn’t slippery to the touch and has a slightly tacky feel.

Rust Blocker Gel doesn’t just protect steel and iron from rust. It also protects other metals such as aluminum alloys, copper, magnesium alloys, silver and solder.

This product is environmentally and user safe. It is non-flammable, non-toxic, non-polluting and biodegradable.

16 oz. spray bottle. Manufactured in the USA according to ISO 9001 standards.
