Napier VP90 Anti-Rust Patch

The Napier VP90 patch is designed to protect guns and other metal parts from corrosion whilst in storage. VP90 vapour deposits an invisible mono molecular coating on any metal surface leaving other materials totally unaffected, it will not dry wooden gun stocks. The mono molecular coating acts as an impervious barrier to moisture and other corrosive elements, regardless of the humidity. Protects a 35.5 Cubic foot area for over a year.
