At my first attempt in adding epoxy eyes to my stock plugs(Gibbs etc.), I have been successful at not chipping the paint etc.
However I do have a couple of questions.

Im using good forstner bits to drill the eye holes. I think I may have been going too deep? How do I know when to stop?

I wrap the plug in a towel and put it into a vice but the soft wood of the plug gets creased(damaged). Any way to prevent?

Finally, what should I use to glue in the eyes and what can I coat the exposed wood with, preferable paint? and what can I use to coat the whole plug(which is usually old and used) to waterproof it. If you can give me brand names that would be great.

Sorry for so many questions. Thanks in advance.
