USA Fluid Surface Rust Remover Absolute Penetrant Corrosion Block Waterproofer is Unlimited StrongArm Fluid

I use this stuff on all kinds of things. It works! I brought my Chevy Tahoe to the salt flats last summer. I treated it with USA fluid from stem to stern. The salt just fell off easily and I have no rust. The salt literally cakes onto the car when you drive on it. This is the solution - but of course you have to rinse the vehicle well after you get home. I also brought some mini bikes and they were treated with the fluid. They weathered the salt bath with no ill effects. This stuff resolves existing rust as well. It's a great penetrant for anything that is already rusty and I've gotten a few seriously stubborn bolts out with it just the same as you might use a product like PB Blaster. This stuff works better!

The product worked well for the old machines I have been refurbishing. I would use this again. The Shop smith machine tables and tubes cleaned up very nicely. I think the product does serve as a rust inhibitor better better than wd 40. I will update when I come across the heavy crusted metal in restoring the next machines. Update 11/9/15- I have a old sander from the 50's, the table was rusted uniformly after 2 days of soaking and light rubbing with plumbing cloth the rust is relenting. the top is coming out very nice. The rust has made a slurry and is disappearing with each removal and reapplication. What would improve the product is to have a gel version of the liquid so less runs away on you. Sometimes you need it to run and sometimes just sit there.

I do like this product, but I also feel that it is hyped up to be a little better then it is. Otherwise it is a great product for multiple uses. It will work okay on some surface rust, if it's very light. It does work very well though to lubricate and free up parts that may not be moving well.

As with most products that claim so much, this one comes up way short. Just a rough version of 3&1 oil but I really wouldn't trust it for any critical applications. DOES NOT REMOVE RUST in any way but I am sure it would help keep rust away once your remove it with something like EvapoRust, etc. Overall highly disappointed but kinda knew that may happen with all the extreme claims.

Save your money. Doesn’t do anything for rust that regular mineral oil doesn’t. Looks and smells like mineral oil/lighter fluid/graphite.

Some of the best stuff out there. I'm on my second bottle. Replaced so many other products and does it better than them. I most commonly use it as a lubricant such as WD-40, however this product has better penetration power, and it remains where you put it for a very long time. It's safe on paint and is good for removing rust from surfaces. This paid for itself when it helped me remove an old rusty exhaust system. Apply to all the bolts necessary and let it work. It breaks old rusty bolts free with better ease than any other product. I swear by this stuff. I wipe down my guns with it. I also use it to prep surfaces to paint. It has many uses and comes with a list of recommended uses. You don't need much and it will last, over a year and less than a quarter gone. Environmentally friendly, I recommend wearing gloves when using. A definite buy!

After reading about this product and speaking with a vender at a motorcycle rally about it, I decided to order it and was anticipating all of the applications I could use it for. The first thing I tried using it for was simple, just spray it on my truck battery terminal posts to keep them from the normal corrosion that develops. Unfortunately my first experience with it was not a good one. It had to do with the spray bottle more than the product itself. When I tried to adjust the spray bottle to a mist I couldn't. It seems the only way it comes out of the bottle is a stream. This can make applying the product to smaller parts, etc. very frustrating. It also leaks out of the spray handle getting on your hand, and in the process wastes some of the product. The consistency of this product is like a light oil, which may have something to do with how it comes out of the sprayer. I thought maybe it was just a defective sprayer on the bottle, so I bought an empty spray bottle at the local Walt-Mart, and transferred the product from the original bottle to the new one. I thought this would solve the problem, but it didn't. Same result. ??? All I can figure is that it must be the consistency of the product that is causing this. In any case, it is very frustrating in that it causes a mess all over your hand you're spraying with and wastes the product which is not cheap. This has kept me from trying the product on other things I'd like to, so I'll have to try and figure a way out to apply it without the mess. I'll update my review after I've been able to try some other applications. I can't say much about the product itself and it's usefulness at this point. Word of warning: where ever you're applying this product be aware that it has the consistency of light oil and can stain, and have a rag handy in case you have the same experience I've had with applying it.

I was planning to purchase new motorcycle rims because they were a little rusty until I heard about this product. So I gave it a try. This stuff works. The heavier the rust the harder you have to scrub. But it will take it out. Cleans light rust with ease. Not sure if it does everything else but it will remove rust. Good product. Thanks.
