Justin, see Brad's response on page 3. Very smart idea, I do not want to deal with the lacquer on the inside of the bores.
Oscars articles are in The double gun journal spring 2003, summer 1997 and Fall 1997.
I can only speak to what I do in rust bluing for plugging the bores. I use 36" lengths of 5/16" threaded rod through the bore with a rubber stopper on each end (with a hole drilled through them) and a washer/nut on each end holding the stoppers in tight. I buy the stoppers from my local Lowes. The hole in the rubber stoppers is drilled also 5/16" so the fit is tight around the rod. But there is enough still there for air to vent. I can always see bubbles coming out when in the water. The amount of water that is allowed in is minimal. I use the Mark Lees Express Blue which is very fast acting. I can do a set of barrels from white metal to finished in 5 hours. So I have no worry about water in the bores causing any issues. When I pull the plugs there is just water droplets in the bores which clean out nicely. However, if you are doing a slow rust process taking many days, I would not recommend allowing any water to sit in the bores.
I personally believe that once anyone uses Mark Lees, they will never go back to anything else. Especially if you are doing a lot of barrels. The results are just fantastic and the working time is so quick.
I can only speak in regards to anything from the point of my own experiences and I would not expect anyone to take it as law.
For etching, you will want to plug with separate stoppers (rubber or wood) that will not allow anything in.
