Napier Super VP90 Corrosion Inhibitor

The Napier V90 Corrosion Inhibitor Patch is a proven, long-term rust protection solution trusted by over half a million shooters worldwide.
Designed to protect firearms and metal equipment in safes, cases, lockers and storage containers, V90 works using advanced vapour phase corrosion inhibitor (VCI) technology.
Once placed in an enclosed space, the patch releases a protective vapour that travels wherever air can reach, depositing an invisible mono-molecular coating on exposed metal surfaces.
This protective film bonds to metal only, leaving wood, leather, plastic, glass and optics completely unaffected.
Unlike desiccants or heaters, V90 does not absorb moisture, meaning it won’t dry out wooden gun stocks or cause cracking and splitting over time.
The vapour barrier actively shields metal from moisture, condensation and corrosive elements, even in high-humidity environments.
Each Super V90 patch protects up to 1 cubic metre (35.5 cubic feet) for over 12 months, providing reliable, maintenance-free corrosion protection.
