Supco MO44 Rust Buster Liquid Penetrating Oil

It worked, on one bolt that was stuck, didnt work on a 2nd stuck bolt.

This is awesome, cuts through rust esily

I like this stuff , it really works good if you have time to leave it sit overnight has saved me many times from drilling.

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

Invaluable tool for rusted or corroded bolts

This stuff really worked like a charm!

Good penetrating oil.

Bought this because of frozen prop shaft stuff box and within less than a hour I was able to easily break apart the the nut from the shaft housing. I give it an A+

This worked great getting some rust off of one of my magazines that rusted.

This stuff might as well be water in a bottle. It has absolutely no effect on my rust anyway.
