If my rifle is submerged in salt water its getting shaken out and lubed as soon as possible at the very least. If the humidity causes it to get a little surface rust wipe it down. The big thing is to keep the operating system lubed with something...Empirically i can't say if motor oil x is better than gun lube y.
