Supco MO44 Rust Buster Liquid Penetrating Oil

This product didnt work for my situation. I went by the instructions and it didnt work.

You can buy in the aerosol spray, but I find this works better as s soaker when you need to use judicially.

Great

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+

I found a bottle of this sitting on an old boiler that I bought out of a house. I decided to use it on the corroded pipe fittings. Every one broke loose and I have been using this stuff ever since. Works best if you can tap or impact the joint after application. Does have a tendency to evaporate easily even when properly capped. Best to store in a secondary sealed container to minimize evaporation.

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

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

I used this to loosen some bike wheel spokes that resisted truing. It works well, well especially if you let it sit for a little time. The product is very thin, as a penetrating oil should be, and really gets into the threads (and everywhere else). The cap design is flimsy, and it doesnt fit well. The company should probably spend another 5 cents and get a cap that fits snugly.

Nothing

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