There isn't a process in refinishing damascus that would require vent holes in the plugs he uses. Boiling water won't harm the bores, and the etchant isn't hot, hence no expansion of air trapped in the bores during that part.
I am sorry.
When he told me that, we were talking about blackening. Whether it is necessary to plug the barrels or not I would not know. I am just an interested consumer.
I know he has used several recipes for blackening. So for the rust process, that may be true as well.
