I've got a 1971 and 1977 Ovation, 12-string and 6-string. Both are in great shape except for a couple of finish cracks where a neck volute would be on some guitars. The crack on the 6-string doesn't bother me because I can't feel it while playing, but the 12-string has a couple of cracks right next to each other and can sometimes be felt in the web of my hand. Neither neck seems to have any yellowing or change in the feel since new. Would the best option for fixing (at least the 12-string) simply be to wax the area around the cracks and sick some water thin super glue into the cracks? I'm assuming the wax would keep any glue from sticking to the original finish. Thanks.
