I think you have to know the product you're using. I have no idea what the Ph in shoe polish is, does it have linoleic acid in it or something? Is linoleic acid bad for gun finishes? I don't know.
Ren wax does seem very safe. But besides being safe, there is the issue of what kind of conditions is the product designed to operate under? Probably for going in a closet, Ren wax is fine. But some car waxes are designed to hold up under the elements.
Another product that I am interested in is NXT Tech Wax. It's the most hydrophobic wax in Meguiar's line. It's specially designed to hold up under rain, and provide long-term water beading. That sounds like it would put a protective coat on a gun finish.
But right now I have enough Gold Class Carnauba Plus to last a lifetime, so I'm not going to drop $35.00 on a can of NXT anytime soon.
