WD-40 Specialist Penetrant 400ml – Fast Acting Rust Release and Protection

The WD-40 Specialist Penetrant 400ml is a professional-grade formula designed to loosen seized, stuck, or rusted parts with speed and precision. Its unique capillary action penetrates deep into threads, seams, and crevices, breaking down rust bonds to free stubborn nuts, bolts, locks, and chains. Unlike standard penetrating oils, this low-odor, fast-acting spray provides long-lasting protection by leaving behind a shield against rust and corrosion.
