I know a lot of sportsmen who have sad tales about putting their guns away for a few weeks with a wipe-down of wd40.
The sad tale has to do with rust-pitting, due to the evaporation of wd40 over time, which is accelerated when wrapped in cloth. The cloth wicks away the wd40, which shortens the effective protection period of wd40.
Even common 3-in-one oil is a better, as both lubricant and protective film.
WD40 is a great penetrating oil, but I don't use it for any other purpose on my knives or guns.
