we recently has a little water in our basement where my gun locker sits. a little bit got into it and the sponge on the bottom was damp. its dry now but i checked yesterday and noticed that my shotgun looks like it had some light rust dust on it, it came off with my hand and a cloth but i dont wanna risk anything being damaged. all of my guns are thoroughly oiled in there barrels and all. i just wanna make sure any moisture or humidity or anything that may have been in there doesnt damage anything. like i said it looks like i got the rust off and it looked like just dust. what can i do to keep this from happening to it again? can i safely leave a thin film of oil on the outside of the shotgun without it doing any damage to the matte black finish?
