I have found that when one uses an Tung Oil finish that the CA discolouring does not show, as the oil gives the same color as the CA.

Here is a picture of an Applewood bowl I turned, it had grafting openings where the two parts had not grown totally together, I filled those with coffee grind and CA, it was finished with Polymerized Tung Oil, and you can not see anything about having used the CA.

I don't know if another oil would do the same thing, as I never use anything else.
