Spalted Maple can sometimes produce tearout that is a PITA to deal with. This one was no exception. But, I gave it a good soaking with Minwax Wood Hardner and that seemed to do the trick. This one absorbed a lot of finish, and I cannot remember exactly how many coats it took. At least 3 coats of DO and at least 3 of poly, then Beall buffing, and I finally got the glass-looking surface I was after. 5" x 3.5".
