Yes the air there is humid. When I was stationed there in GA we operated in the swamps. I think it rained there nearly 300 days a year? Anyways our ammo was exposed constantly to the rain and humidity. However when I loaded my ammo for Alaska I didn't use sealant and it functioned fine. Alaska's weather, and mosquitos, are pretty close to GA's conditions. There's nothing wrong with using sealant, I wouldn't want to use it for long range hunting. But that's a limited area in hunting, especially in the parts of GA I was in. The main concern with sealant for me is forcing it down a firing pin hole while cleaning. It can mix with solvents a create a polymer like substance. That can restrict primer strikes and it tough to get rid of. Just clean boltfaces on any firearm with the boltface facing down while brushing or cleaning. That's what I've done with my EDC pistols/ revolvers and I haven't had any issues.
