Your question is akin to asking what kind of motor oil everyone prefers. You will get as many different replies as there are people to answer the question. That said, I may as well add my .02. I have a golden rod in my safe, and I use either Howard's Feed N Wax or Johnson's paste wax. The Howard's has citrus oil, bee's wax, and carnauba wax in it, and works wonders on wood stocks, especially if they are in need of a little extra moisture. The wax in it works just as well on metal I find. Of course the bore and internals are cleaned and lightly oiled. I also like to use silicone impregnated gun socks on at least half of my guns, if only to keep them from safe dings. My safe is way over capacity I'm afraid, so that's become a necessity.
My safe is in my office, which is 1/2 below grade in the lower level of the raised ranch we live in. In addition, I live in southern Maine, with very changeable weather, and high humidity at times in the summer. So far, I have had no issues at all with rust on any gun. Some I have owned for about 40 years, so something I'm doing works for me.
As I said, you will get a different answer from everyone who replies. Hopefully you can gather enough advice from all these replies to suit your needs, and protect those all important firearms.
Take care, and let us know what you decide.
