foam case cause rust?

[Gwandena]

When I purchasing my new/used 870 I was looking for a case to store it in at home. I dont have the money for a huge refrigerator safe, im waiting till I own a house for that one. The guy at the gun store told me to try not to do long term storage in the foam cases because they can over time cause the weapon to rust. I read here about good way to revome rust Is this true?

YES! DO NOT store firearms in a foam lined gun case.
If you want to protect it, get a simple, cloth "gun sleeve".
Guns are best stored out in the open in a controlled atmosphere (home?).
Foam and faux fleece lined cases are the world's worst about causing rust.

It depends all on the relative humidity where the firearm is being stored. My house stays dry with the humidity usually running in the 40's. So far I've not had a problem with rust.

PH is exactly right. Much depends on the surrounding area and the average humidity. I have a wood frame garage with lots of misc. wood pieces around. I call the wood - slave wood. As the humidity increases, the wood absorbs the moisture. And vice-versa. Same way in the house. I can leave carbon steel out for a year and never get any rust.
On the other hand, I know someone who has an all concrete/masonry block garage with no wood in it and a car parked in it will rust before your eyes.
I was at a buddy's house getting some work done on a lathe. When finished he gets out a bucket and starts coating everything. He said without it the rust would start. Guess what, not a stick of wood in his whole shop, all steel.
What I do is when home, open the gun case to dry completely. Then I put the gun in but leave the zipper open some. Never have had rust on any of my firearms.
Worst thing is to zip a case tight with a gun inside with a damp lining. Rust will start before you get home.

Have to agree it depends on where your keeping it and how much care your giving it. If you put it in a damp room it will rust no matter what.
