Wd-40 Specialist 11 Oz. Aerosol Penetrant

WD-40 Specialist Penetrant is designed to tackle the toughest rust and corrosion challenges. This fast-acting formula penetrates deep into crevices, threads, and seams, breaking the bonds that hold stuck parts together. It works on contact to free rusted nuts, bolts, threads, locks, and chains, leaving behind a protective layer that prevents rust and corrosion from re-forming.
