StrikeHold Prevents Rust and Corrosion. Industrial Strength - Cleaner, Lubricant and Protection For All Metals, Superior Rust Penetrant, Electrical Contact Cleaner. Comprehensive rust protection. Acting as a powerful anti-rust spray, advanced nanotechnology with incredible capillary action ensures deep penetration and complete protection, forming a long-lasting barrier against moisture and corrosion on all metal surfaces, tools, and equipment. Superior penetrant. The advanced synthetic formula is a fast-acting, deep-penetrating compound that cuts through rust and corrosion. It reaches into tight spots and microscopic crevices, freeing metal parts that have become frozen or encrusted. Micro Capillary Action Reduces Friction. Long-lasting dry lubrication extends the life span of metal parts and equipment. It reduces friction and wear on moving parts and doesn't attract dust, sand, or debris, making it ideal for use in harsh environments. Displaces and Repels Moisture. Heavier than water, it bonds to metal surfaces, providing a shield-like protection barrier and an unmatched saltwater corrosion inhibitor. Advanced Electronics Contact Cleaner. Its dielectric strength is up to 40,000 volts, helping to protect moisture-sensitive equipment and circuitry. It also displaces moisture and cleans electrical contacts, improving conductivity and keeping electrical connectors clean. Note - NOT for use on sealing surfaces or O-rings!
