How do you fix a hairline crack in a guitar neck?
Fixing a hairline crack in your guitar's neck is easier than you think. With water, some CA super glue, and a couple of clamps, you'll have that crack bonded perfectly in no time. And, after a wet sand and some buffing with a polish like the Meguiar's Mirror Glaze, the neck will look and feel amazing.
