Dining room table developed hairline cracks in surface in many places and directions as shown in attached picture and looking for a way to repair them. Not sure if it is an epoxy or very thick polyurethane on it that is cracked. Will I need to sand it all off and completely refinish or is there a way to fill these cracks, sand, repeat? I heard of magic with superglue and sanding but would hate to try something and destroy the table or create more work. Looking for help or recommendation for a rock star in Boston who can make the table right!
