Titebond Original Wood Glue
The luthier's favorite aliphatic resin glue, for joints that are stronger than the wood.
Water soluble, it cures overnight, sands easily, and resists thermoplastic "creep" better than ordinary white glues.
Shelf life is 12-24 months if stored in a cool, dry location. If the glue becomes thick and stringy in the bottle, this signifies that the glue is no longer usable.
