XCP Rust Blocker 400ML is a soft, anti-corrosive compound that creates a long-lasting protective barrier for steel, metal, or alloy surfaces against rust and corrosion. It can be sprayed, wiped, brushed, or dipped, offering a soft tack that resists cracking. The film's bonding with the metal surface ensures market-leading corrosion resistance. For best results on coated and/or non-metal surfaces, test on an inconspicuous area first. Key features include industrial-strength protection, market-leading performance, a clear, flexible film, versatile application, and moisture displacement.
