Some advise using both. Personally, I've not used a bore coating as of yet, and stoppers seem fine, although when I'm carding under water after etching, they've been known to be knocked out. Since it's just water, not so much of a big deal.
One fellow I talked about this along the way, doesn't use anything for the bores. His etches sounded brief, and he said it cleans out the bores. In his process he scrubs the bores during each cycle, so I suppose nothing potentially harmful is allowed access to the metal for long enough to be an issue.
I appreciate when we work together sorting this out. There's more than enough work to go around, and we're all the better for it when we collaborate. This process has such a high degree of variability due to materials and environment, all of those doing it have their own tweaks, and some are competitive about their secrets. Sharing is better. Thanks to all for contributing to the discussion.
