Supco MO44 Rust Buster Liquid Penetrating Oil

Unstuck a rusted bolt on the boat engine that most said could not be done.

Assume this would have worked on an application where the oil could run downhill. My application was more horizontal so no much of the penetrating oil soaked into the rusted threads.

Very good product, it works.

Nothing

Invaluable tool for rusted or corroded bolts

Excellent product. I had two very rusted screws and bolts and it only took two minutes after I squirted it on.

Ive used this several times already and theres no question it is superior to other penetrating oils.

penetrating.....

Bottle is half, of the liquid and looks used , you cannot return this , so be aware if you buy it

This is the best by far. Hard to find. Amazon prime!
