alt Hacker NewsI thought it was mostly meant to protect against rust due to moisture in the ambient air so I put it on tools in my basement. But if it's evaporating, maybe it's not so great at that.
But yea, like Coke or McDonalds, the brand is probably worth far more than the secrecy of the recipe.

My stepdad was a drywall finisher, those crews washed the drywall off their tools with water, then got the water off (prevented rust) with WD40.
Difference being, they applied it every day, and specifically to prevent rust because the tools were wet. But man did they love it. Went through a couple cans per week I bet.

I think that Project Farm did a video on rust prevention formulations. I don't remember how WD-40 fared.
There is a product called BOESHIELD T-9 which actually does, reportedly, work for this. It was suggested in some thread years ago and I got a can, it appears to work well enough keeping rust creep off my ancient drill press table.
