WD-40 Specialist Penetrant - 13.5 oz.

WD-40 Specialist Penetrant is a fast-acting penetrant with capillary action to penetrate deep into crevices, threads and seams to break the rust bonds that hold stuck parts together. It is a low odor formula that 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. Now the job is even easier with our proprietary allowing unlimited access to hard-to-reach places.

(NOTE: The adjustable precision nozzle is only available on the 13.5 oz option, the smaller cans just feature a basic sprayer.)
