KROIL Kano Aero Penetrating Oil, 10 oz. aerosol (AERO)

Worked Great. Arrived as promised.

Works like a dream

I had a particularly difficult union to remove with severe corrosion on it. Tried well known penetrants but they did not work, so cleaned them off with a solvent cleaner and applies AeroKroil. After three days of reapplying it, the union was able to be removed. Brilliant product!

I have been using this product at work for a long time. I have used it enough to know that if you you put this on something and let is soak for a bit, and it still does not come apart, get a torch or saw out because that is the only way it will come apart. This stuff is pricey for sure, but worth it. It chemically has a molecular size that is smaller and better for soaking into corrosion and rust, so much better than the kerosene based WD type products. All of the other reviews that are not a 5 star are not about the product is is about how it was damaged in shipment.

Used my 'normal' penetrating oil on a seized bottom bracket on an old Halfords steel bike. Put the bottom bracket in a vice and turned the frame, absolutely no joy. Bought some of this, a squirt a day over 4 days, then the same vice technique and it came loose first time. Expensive but worth it for an amazing penetrating oil.
