Uh oh, here we go. Everyone coming on and saying they havn't had any trouble. You guys want to to wait until there is trouble?

Easy fix, as I have mine in a basement also. Get yourself a humitity guage or two, (they can be inaccurate). In the winter, probably no issues, but the spring and summer might be bad. If the levels get above 45%, see the if the rod is enough. If that don't work, get some some of the silca gel, if the levels still go much over 50%, you better by a dehumidifier and put in there.

I have seen too many people say, "i never had a problem", and then all the sudden one day they find surface rust cause they kinda got out of shootin or something for a few years. If you know its humid, waiting for rust is silly.
