I have a F grade Lefever with damascus barrels circa 1890. If holding the gun in your hands the barrels look really nice(no rust visible). I recently took some ultra close up pics using 2-250 watt work lights. What showed up was some rust spots that I had never noticed before. SO, my question is, are these spots something that should be dealt with and how can I do this, or is keeping it cleaned and stored in a safe adequate so nothing further happens. I am not extremely knowledgable about Damascus and would rather leave it alone compared to the chance of doing any harm. I had heard of some thing to do but thought I would ask here before trying anything.
