Bore Tech Shield XP Rust Preventative offers superior long-term protection against rust and corrosion, specifically formulated for firearms exposed to extreme weather and corrosive environments. With over five times the rust and corrosion protection compared to competitors, Shield XP excels in durability, surpassing 500 hr in ASTM humidity testing and 100 hr in ASTM salt spray testing. Safe for all metal types, it forms a dry, non-oily, non-gumming, and invisible barrier that preserves firearm accuracy while providing comprehensive protection. Unlike conventional rust preventatives that leave a messy residue, Shield XP penetrates deeply into metal pores, displacing moisture and neutralizing corrosive byproducts. It seals the surface with a semi-dry film that resists sand, dust, dirt, and debris. Featuring a light coconut scent, Shield XP is available in a convenient pump spray bottle for direct application or use with a gun cloth for wipe downs. This product delivers the ultimate defense against rust and corrosion, ensuring the longevity and reliability of your firearms. Spray Cap for Pump HDPE plastic bottle (treated)
