As much as I do like Renwax, I do not use it on guns for the most part. I shoot my guns regularly and when I put them away after cleaning them I wipe them down with an oil cloth - that's it.
Since Renwax works best with a clean and oil free gun and I choose not to remove the protective oil, it wouldn't work very well anyway. I do use Renwax on other objects that do not have to be oiled to protect them. I shoot every week and since I usually shoot multiple guns, I try not to make things complicated anymore than necessary. If they were in a lighted museum display case - the yes I would use the Renwax on them.
