I live a few miles SE of Beagle333 a block from the Chattahoochee river. Humidity is always horrible here. I inspect my firearms at least monthly, and those that make the trip to the range and get fired get a good cleaning in the shed, starting with a boresnake. My 9mm pistols get taken apart and thoroughly cleaned, my revolver is a SRH that I don't disassemble but do thoroughly clean, and my rifles get some Outers Bore Foam after a boresnake has been through them, then after a wait they get the treatment with Hoppes #9, Kroil, and a final squirt of RemOil. It' the best rust preventative I've found, even better than CLP or Ballistol.
