Supco MO44 Rust Buster Liquid 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 is awesome, cuts through rust esily

Helped get a stuck shower-head loose. Good to keep a bottle in your toolbox.

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.

Used it for some gun cleaning for some old rifles. Worked well but left some discoloration to the metal, wouldnt say for sure it was due to this product but just a heads up.

I had two rusty hinges on a ramp for a trailer. I Used this on both. One hinge came loose in a matter of 15 minutes. The other hinge required several applications more and finally heat and a mallet to loosen the 2nd hinge. I was kinda impressed with the first hinge loosening up so quickly.

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!

arrived not well sealed so 1/3 was gone
