I see no point in dessicants, if you keep your guns coated with something and it is an area that is dry, like inside your house. Well I admit I have not stored guns at a beach house or in the full tropics but in this neck of the woods dessicant would be a last resort for something like storage in a basement or garage or worse. Modern climate control homes do not have the high humidity or temperature fluctuations to cause a cared for gun to rust. Cared for, that is.
