Thread: Stock refinishing - hole filling

Thanks for the comment omark.

Other question: I have removed the old finish which was a vanish/polyurethane of some sort, and now back to clean wood. However lots of dark stains in the barrel cannel and in the bolt recess. Am I right in assuming that this is soaked in gun oil? How do I get it out of the wood? Do I need to get this out given it will not be seen once its all back together?
