Earlier in the thread I mentioned my preference for rust blued finishes. I realize the average reader may think it’s for nostalgia (in part) rather than because it is one of the best, most lasting finishes you can get. (Just like oil finished stocks)
The average reader is probably unfamiliar with how to service, maintain, and conserve their fine arms. Most gunsmiths today are in the same position, having entered the trade as armorers for black guns.
Every gentleman needs a list of about $150 in materials to always have around to care for their guns. I can’t tell you how many people are astounded how much better condition their firearms are actually in than the think looking at them.
the materials list you need to have, the same materials that Boss, Purdey, Westley, and Holland would have had if you sent your gun in for annual service, are as follows:
0000 Bronze Wool
kroil or other extremely fine oil
Renaissance Wax
A couple fine toothbrushes
bronze and nylon brushes
Many micro fiber cloths and lint free T-Shirts
A bottle of oil finish
With the above list of items, and a very gentle hand, when used properly, you can do no harm.
That barrel may have rust ON the finish, not under it. 0000 bronze wool is harder than rust oxide and dry grease/oil, but softer than bluing and steel. Cleaning up a barrel early in its corrosion is easy. For this reason, I’ve had no issue using best guns in the rain and inclement weather. Clean and arrest corrosion early and you’re perfect. Arresting it 50 years late, you may get 80%-90% of it.
Anyone can add a bit of oil finish back to a gun stock without ruining it. Adding 5 layers (10 drops) every couple of years means you’ve not injured the original oil, you’ve just layered up what use has taken away.
All the modern finishes are prone to their own maladies and we don’t really know what they’ll look like in 20-50 years. The traditional finishes and their care and conservation have 200 years of history behind them.
Something to think about, and by doing your own conservation and cleaning (not restoration or gunsmithing) you will gain better insights into your guns, add to their longevity, and ensure they work for generations to come.
The modern gunsmith is ignorant to all of this because they are not well read on classic processes and they were not trained in the traditional ways. The experts still exist but they are gaining in age rapidly and dying out. You can learn how to maintain and care for fine arms without injuring them just as the greatest gun makers have for their clients for 100s of years. This is why classic British arms look so good...minor care for 100 years has sustained them in ways that have kept them in great condition after incredibly amounts of use.
Above all else, do no harm, and you’ll be just fine without Cerokote or any other new treatment to arms. Always remember, the best Germans and English a century ago had access to many similar technical innovations as we are seeing adopted today, they didn’t reject such solutions because they didn’t exist in some form back then, they rejected them because they knew something we’ve ignored today due to hubris or ignorance today as a gun owning society.
