Minimizing loss of damascus pattern...

[Drew Hause]

Courtesy of Joe Wood for protecting damascus barrels after cleaning:
"Formby's Tung Oil is by far the best metal finish I've used. It is very easy to apply (or remove), dries quickly, and seems to have "miracle" restorative properties when applied to faded damascus barrels.
Place a long wooden broom handle in the breech of one tube and tighten the handle in a vice so the barrels are horizontal. Wet a 4 inch square cloth patch with the oil and wipe it on, moving quickly. It might help to rotate the tubes using another wooden dowel in the muzzle of the other barrel. One patch should do both barrels. Let dry for 3 to 4 days then admire your work."

John, Doc Drew has it covered. I have used it on three damascus guns...works great! The only advice I would add is, use in very thin coats, and make sure cloth is lint free. George
