Supco MO44 Rust Buster Liquid Penetrating Oil

Nothing

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

I dont know what I was expecting, maybe a miracle. I have a shower head thats been in place for 24 years. I couldnt BUDGE it with a wrench and vice-grips. I tried WD-40 twice, allowed time for it to soak in with no luck. Nearly busted my gut trying to loosen it. Nothing. I dont know whats in this Rust Buster but it seems more volatile (thin) than WD-40. I tried it twice, both times letting it flow in to the threads. Nothing. Doesnt bust anything. Worthless. I must say that I feel that this expensive product seems to be designed to separate nothing but me from my money.

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

Looks like just water! Cant tell if it works or not

Works like a charm on brass bushings and leaves them slightly lubricated without the chance of any build-up to occur like how it does with 3-in-1 oil

This stuff really worked like a charm!

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