I have a model 13-1 and a model 38. I am the 2nd and 3rd owner and neither have been safe queens.I am carrying both of these more and more because I have confidence in them and my ability with them. I am wondering what I should do to protect these. I have heard people speak of waxing blued guns. I wonder can I use a high grade auto wax for this. I normally just wipe them down when I think about it with a silicone treated cloth. I clean them and them coat them with a light coat of oil such as rem oil or lucas gun oil. I just want to take care of these that I want to take care of me.
