I got a killer deal at a local shop on a brand new Epiphone Casino with seemingly minor shipping damage. The neck has a hairline crack coming from the nut that appears to be only in the finish, see photo. The head-stock seems stable, and it was perfectly in tune when I got it home, so I'm optimistic the wood is intact. Plays great. Will pop the strings off tomorrow and hive the head-stock a good wiggle to confirm. I am hoping to conceal the crack, or at least smooth it out. What is the best approach for repairing poly finishes? I was thinking about covering the crack with some Black Tint StewMac Super Glue, and then sanding and buffing. Would this be an appropriate approach? Figured for $270 price tag, picking up this guitar would be a fun project. Thanks in advance.
