10-12 years ago, I had a set of 10 gauge Prussian Daly hammer gun 3 Iron Hufnagel barrels re-blacked. The guy who did it is no longer in business, but did a great job. However, when I received the barrels they were shiny as a candy apple from the lacquer he put on them. I promptly took some 0000 steel wool and lacquer thinner and cleaned them of all of it. Did not harm the pattern at all. They looked much better and authentic after a wipe down with a light coat of Clenzoil.
