I've ordered some PlusGas as recommended for the future... I'm 90% sure that was a rhetorical question but I guess you'll have to keep saying it as long as there are noobs like me who didn't know any better UNTIL SOMEONE TOLD US
There are possibly 2000+ uses for lots of things. But there is only one use for proper penetrating oil. Penetrating. WD 40 is primarily a water dispersant that is what it is for. It will never be as good as a proper penetrant oil. It is simple not as good as the proper stuff.
