The Napier VP90 Super Shield Corrosion Inhibitor Spray (750ml) provides heavy-duty metal surface protection against rust and atmospheric corrosion in unsealed, high-exposure environments. It combines Napier's vapour phase corrosion inhibitor chemistry with a contact barrier film that bonds instantly to ferrous and non-ferrous metals upon application. Once cured, this flexible barrier adheres firmly to resist rubbing off while protecting metal surfaces subjected to direct rainfall, heavy condensation, and saltwater exposure.

Key Features

• Dual-Action Formulation: Combines proprietary VP90 vapour phase corrosion inhibitors with an active contact barrier film to seal exposed metal surfaces.
• High-Resilience Barrier: Forms a bonded, flexible protective layer that remains intact under permanent exposure to salt spray, rain, and humidity without rubbing off.
• Extreme Moisture Resistance: Built to maintain surface adhesion and prevent oxidisation in conditions reaching up to 100% relative humidity, as well as direct contact with boiling water up to 100°C.
• Dual Nozzle System: Supplied with two interchangeable spray nozzles, including a wide-angle nozzle for broad surface coverage and a jet nozzle for recessed mechanisms and hard-to-reach hardware.
• Broad Material Compatibility: Bonds safely to all ferrous and non-ferrous metals, engine components, tools, and automated clay pigeon traps without degrading the underlying metal substrate.

Who is the Napier VP90 Super Shield Corrosion Inhibitor Spray 750ml for?

• Hunters and outdoor shooters — requires a heavy-duty firearm corrosion inhibitor spray supplied in a 750 ml aerosol canister that maintains a bonded protective barrier in environments reaching up to 100% relative humidity.
• Automated clay pigeon trap operators — needs an external metal corrosion inhibitor spray that withstands continuous unsealed atmospheric exposure, direct rainfall, and extreme thermal contact up to 100°C on outdoor trap components.
• Marine and automotive owners — requires a 750 ml corrosion inhibitor barrier spray that prevents saltwater oxidisation on exposed non-ferrous and ferrous engine parts under permanent ambient moisture.

Less suitable for: Firearms stored exclusively in dry, enclosed safes or sealed cases, where standard vapour emitter sachets or light gun oils provide sufficient protection without building a barrier film; and precision internal trigger actions, where dedicated light mechanism lubricants should be used to prevent gumming.
