Ken Keoughan replies: Cut it into turning blanks and double-coat each blank with Anchor Seal. Remove the pith before sealing. If you want to preserve a whole log, Anchor Seal the end grain (double coat), and any open cuts such as where a branch might have been cut off. Maple, cherry and ash are all pretty stable. Birch is not. Do not coat the whole log with Anchor Seal unless your wife is a direct descendant of “Old Man Seal.”
