XCP™ RUST BLOCKER™ is a powerful soft corrosion protection compound, providing the next level in corrosion protection. It creates a long lasting barrier to protect any steel, metal or alloy surface against the effects of rust and corrosion. Use it on exposed metal surfaces, including engine components, suspension units, undercarriage, box sections, chrome, chains, motors, shafts, spindles, as well as tools and equipment for shipping or storage, and many more! XCP™ RUST BLOCKER™ is non-conductive and so can be used on electrical connections
