Many years ago when WD-40 first appeared on the market it was touted as being an excellent lubricant for firearms, however, it was quickly shown to be not a good lubricant, it would dry on the moving parts causing the weapon to jam..
Maybe it would be a good idea to again tout it as a gun lube, thereby causing a lot of the weapons terrorist use to jam.. Cheap gum control.
WD-40 is an excellent winter starting fluid for 2 stroke engines, chainsaws, etc., and it works great to remove decals from painted, chromed surfaces.
