All types of foam used in cases are different. Some won't absorb and hold moisture next to your gun but some will. If you store a nice gun in any kind of soft fabric or foam case you are taking a chance. When I worked in a gunshop I saw far too many nice old guns ruined by rust from the owners storing it in a soft case. Under the bed. Or in their basement. Cases are for transporting the gun, not for storing it. Store your gun with a thin coat of oil in open dry air. Put it in a rack or a safe but not in a case. Cases were never intended for long term storage, they are intended only to get the product to you in good shape. Ask any gunsmith about storing guns in cases or cardboard boxes. All it takes is one humid day to ruin your gun.
