Penetrant with Smart Straw, Penetrant for Metal, Rubber and Plastic Threads, Locks and Nuts, Industrial Strength Fast-Acting Formula, 11 Oz.

This WD-40 Specialist Penetrant is a rock-solid 5-star product that belongs in every garage, shop, and toolbox. The fast-acting formula works quickly on rusted bolts, frozen nuts, seized locks, and corroded threads that would otherwise require a breaker bar and a lot of frustration. It penetrates deep into tight threads and hard-to-reach areas, breaking up rust and corrosion without damaging the surrounding metal, rubber, or plastic—which is a big deal when working on delicate or older components. The Smart Straw applicator is excellent for switching between a broad spray and a precise, targeted stream exactly where you need it, with no straw to lose track of. Whether I'm working on the RV, vehicles, or shop equipment, this penetrant has bailed me out on more than a few stubborn fasteners that nothing else would budge. Industrial strength performance in a convenient aerosol can—it does exactly what it promises and does it well every single time. Highly recommended.

RE: WD-40 Specialist Penetrant With Smart Straw, Penetrant For Metal, Rubber, And Plastic Threads Excellent product and by applying repeititively for several days, saved a dozen expensive locks for re-use saving lots of money. Also works really well on loosening up manifold bolts to remove boat manifold bolts in order to remove manifold gaskets and then install new gaskets able to save all bolts. Will use to loosen boat control cables to prevent stretching and destroying them as well saving lots of money.

Works great, everytime. No disappointments here.

ALWAYS WORKS GOOD

WD-40 works great

Good Product, Good Value

I don't use it often (I prefer PB blaster) but it definitely came in handy and worked well for what I used it for. Every garage should have a can.

Very handy, good pressure - definitely an improvement
