KROIL Original Penetrating Oil, King Size, 13 oz. aerosol (KanoLab Aerokroil)

Kroil Review I use Kroil at work for a major airline, and it's hands-down the best penetrating oil I've ever used. Whenever we run into seized bolts, nuts, plugs, or any other stubborn fittings, the first thing our aircraft mechanics do is soak it down with Kroil. It works 100% of the time — flawlessly. No matter how stuck or corroded a fastener seems, Kroil finds its way in and breaks it loose without damaging threads or parts. It's become a go-to tool in our maintenance routine, and I wouldn't want to be without it. Simply put: if it's stuck, Kroil will free it.

I was introduced to your product by United Mechanical in Waltham, Massachusetts. They gave me a can and said this is the best product on the market. I have to tell you that I am amazed. I was do impressed that I put them as a premier vendor for our company.
