I was watching a video where this fairly knowledgeable individual mentioned that he used some sort of wax to protect the finish on his blued handguns. It made a bit of sense to me. Does anyone else do this?

I question wether the wax would endure the temperatures in some areas, but it seems it would offer protection from humidity and perspiration. Living in south LA, protecting a blued finish is always a concern. Back in the 70’s, I had a shotgun( Rem 1100) that developed some surface rust in the time it took to leave the blind and unload the truck at the house. Lesson learned. So, I’m all about taking whatever precautions available to protect the finish, especially on my expensive S&Ws.
