Anybody using WD40 corrosion inhibitor?

I was working on a customer’s gun safe and he brought it up. He said he uses it on the outside of his guns and it prevents surface rust. A friend of his tried 4 different products and posted time lapse pics. He almost polished four pieces of steel and sprayed each with a different product. He took pics daily, then weekly, then monthly for a year. The WD40 corrosion inhibitor was the only one that had zero rust on the steel. I’m going to get some and give it a try. Sounds promising.

I wonder how easy it is to remove.

WD -40 is advertised as removing moisture.
It also has detractors who claim it can get gooey under some conditions.
There’s plenty of reviews about it with a web search.
They might be worth a look before using it.
Just a thought.

I could be wrong, but I think he’s talking about WD40 branded “Specialist Long Term Corrosion Inhibitor” spray:

So it’s not the normal WD40 spray but something different from the same company if I’m understanding it correctly.

I use regular WD 40 on my assault shovels.

Do NOT use regular WD40 on firearms. When it dries out it leaves a.film of varnish like stuff.

Yes it does, not good for moving parts. fine for inanimate objects like AS’s.

As stated it is the corrosion inhibitor, not regular WD40. I was thinking about using it on the OUTSIDE surface of the barrel and receiver as a rust preventive. I would not use it on moving parts.

While I do agree, using normal WD-40 for internal workings of a firearm is not recommended, using it on the outside could be suitable for rust prevention. I use it all the time on the outside of my barrels and receivers. I have not used the Specialist Rust inhibitor spray on my firearms, but have used it on other equipment and does a very good job at protection from rust.
