 * The solvents in cyanoacrylate and those needed to clean up cyanoacrylate and epoxy are destructive to traditional lacquer, varnish and shellac finishes, making these glues poor choices for many applications. Most epoxy loses strength at the temperatures reached in hot parked cars, so it may not be the best choice for highly stressed applications around the bridge and neck. 

** These glues make it impossible to disassemble dovetail neck joints!
