I haven't tried the goldenrod but was thinking of getting one, guess that's a must now. Anyway, I live in Michigan where the humidity is usually pretty high all summer long, and all I do is make sure that pull all the guns out of the safe once a month, and wipe them with a little gun oil. Only problem is if you forget to do it, or get lazy and don't do it. I guess you could Cosmoline them, but that's messy, both to put on and take off. Sounds like the goldenrod is the way to go.
