Waxing "Safe Queens" would be fine - but I don't have any.
I shoot ALL my guns and for me to wax them, clean after shooting, remove oils and solvents and re-wax is just more trouble than it's worth, at least to me.
After cleaning a firearm I just give them a wipe down with a new lightly oiled patch and put them back in the original box. Each gun gets wrapped in the VOC anti-rust paper (bought a bunch from S&W) and not only does the VOC paper help prevent any rusting it also keeps any oil on the gun from ruining the box, foam, styrene, etc .
I suppose if I was to shadow box frame a gun to hang on the wall for display, waxing would be the way to go but just don;t see it as practical for guns that actually get shot.
