Surface Finish for Damascus Necklace in Fit and Finish Posted August 10, 2016 OK this will probably sound weird, but I have done this, not on damascus but to preserve the flame patina on tongue drums. Turtle wax for your car. I have drums over two years old that get regular play - sitting in your lap hands all over them - with no loss of color or oxidation past what was put there with the torch. Give it 3-4 coats and rub it in till it shines each time, and your good to go. I've tried a similar experiment with furniture polish, and it works too, but requires it to be redone once a month or so.
