It just says <25. What is the volatility of that Hydrocarbon?
Spray it on a flat surface and leave it out in the sun all day. How
much film is left?
I have never seen it remove corrosion other than a film of surface rust
that can be wiped off. , nor will it prevent steel from rusting on an
antenna. Spray some steel U-bolts, and just hang them on a tower. How
many days before they show signs of rust. I recently rebuilt a damaged
antenna. About half the nuts twisted off the threaded portion. WD40
didn't help. PB-Blaster did

I've often wondered why WD40 became associated with a rust buster/penetrate.
It does penetrate, but contains no lubricant and evaporates relatively quick
leaving thing as they were before the application. However, it is good for
freeing up small engines that have seized. Pull the plug, squirt in about a
tablespoons worth and let set over night.
Bur, rusted bolts, not so much.
