WD-40 Specialist Penetrant with EZ-REACH , 13.5oz. WD-40 Specialist Penetrant with EZ-REACH penetrates threads and seams to free stuck, frozen or seized equipment and parts. The low-order, fast-acting formula penetrates 50% faster than the competition*with capillary action that removes rust and corrosion on threads, locks, chains, nuts and bolts, while leaving behind a protective layer that prevents rust from re-forming. This industrial-strength penetrant works on contact and comes with an 8 inch flexible straw for more precise applications in cracks, crevices and other hard-to-reach areas. Whether you re working with metal, rubber or plastic, this heavy-duty penetrant can tackle all of your tough jobs with ease. *Test Lab: WD-40 Co.
