I have an "extra" new in the box Marlin 1895 SBL that I am not ready to part with just yet. Any ideas out there on best long term storage techniques? My safe has a dehumidifier rod but I live in a high humidity climate. Should I give the metal surfaces a good coat of oil and put the rifle back in its original packaging including the plastic bag and store in my safe? Or, are there other methods to ensure the gun remains in "new condition"?
