You're omitting two steps. After the rustings, the barrels need to be cured, usually by soaking in an oil, then they are degreased, polished, and finally lacquered.

Etchant is best used in a tank, such as a PVC tube. I believe Stallones has said he brushes his on, so it must be a matter of technique. I brush on vinegar for a clean up, I do it very quickly.

I prefer wood to plastic, leather to nylon, waxed cotton to Gore-Tex, and split bamboo to graphite.
