Kroil Original Penetrating Oil (Drip-8oz Can-Single) | Penetrant for Rusted Bolts, Metal, Hinges, Chains, Moving Parts | Rust, Inhibitor (KL081)

It worked well for the job! Good product!

I like this because it works. It helped loosen the stuck header bolt. The mechanic used all the other brands of rusted bolt removers and used heat and nothing was working and was going to stop the project. A man came to their shop and after hearing the issue he went to his house & came back with this oil. They told me it took about an hour soaking and the bolt came off. So happy, now my header have get control. I very highly recommend this product if you want to save money and time.

Been watching rebuilding projects on You tube, and they always swear by this stuff as the best, so I decided to check it out. They are right, forget about other sprays, this stuff gets down to what is sticking and makes it work like new.

This stuff is amazing. Use it to loosen screws, use it to help break a blue loctite bond, use it to season a barrel. Or three.

It's impressive the way it climbs rusty threads . I haven't yet put it to any real test, but I will say it's a far cry above most penetrating lubricants in the way it moves it's way up threads . It seems it will find it's way in between the nuts and bolts . It also doesn't dry up and evaporated as fast as several others I keep on hand .

The can arrived without the spout shown. Instead, it has a non removable spout in the middle of the can.That makes it impossible to dip a brush in. Also, the shorter spout is not as convient to use. The product itself is excellent.

I have used this product ovet many years,and it has not failed. Apply the product and vibrate, lightly tap, and it creeps to where it needs to be. I have purchased several times.

Haven’t used but happy it’s what I ordered
