Great for long term firearm storage

I was using 0w20 Full Synthetic Motor Oil but I tried this in a high humidity area and it works great. I now spray all of the tools, saw blades etc in the shed when storing. Works fantastic.

Excellent Long Term Corrosion Protection

A friend familiar with the product recommended it. I cleaned rust from a shovel that we leave out year round to clean up after the dogs, and then applied Specialist Long Term Corrosion Inhibitor ONCE two years ago. There is still a "wet" residue of the product on the shovel but NO RUST. I've applied it to mover blades, woodworking machine tables, hand tools, etc., by spraying on a rag and applying a thin film to the surface needing protection, and rust has yet to reappear. I've sprayed it on suspension components and underbody areas of my Jeep that had light surface rust two years ago, and the corrosion has not spread. This is one product that works as described.

Stops rust and corrosion

I live in the Florida Keys. A very hot, very humid climate laden with salt air. The damp,salt air is highly corrosive. I spray WD-40 on all my lawn, garden construction equipment that have metal after each use. A 3 year old gas powered hedge trimmer still looks like new. My old one rusted rusted and was ruined. I use this for my saw blades, drill bits, tree saws and all keep their new like appearence and sharpness that otherwise would have rusted, dulled and been no good.

Not as Good a Paint, But...

I've found this to be exactly what it's title says it is. Not rust protectant, or remover. Just a way to prevent rust from developing. Doesn't stay on long in outside conditions, but does inside or in areas not exposed to weather.

Works great prevents rust and its weldable

While working on a Chromolly race cage we stored  it outside in rainy weather under a tarp for 2 days , pulled it out with no rust. And best of all it welded up great with no problems.
