Modern stringed instruments are finished with a choice of polyurethane 2 component lacquers, nitrocellulose in some cases, Tung oil, Tru oil, Linseed oil, Beeswax, Shellac, Lemon oil e.t.c. The fingerboards are built from Maple, Rosewood, Ebony, Cocobolo. While Maple gets whatever finish is on the back of the neck (usually made from maple or mahogany), Rosewood, Ebony and Cocobolo are usually untreated, due to their high oil content and natural water resistant properties. However, these can often get dry, shrink or crack, so a treatment of Lemon oil is recommended. But if the guitar/violin is used often, the wood soaks the sweat from the hands and it's usually fine trough the (100'ts of) years...

I have built several electric guitars and basses, and have used some of these finishes (nitro, Polyurethane, linseed, beeswax...)

Superfly you are right, I use nitrocellulose on guitars I build(acoustic and electric solid body). My guess would be to use polyurethane. it would probably be more stable and not check or crack up after a while. Dan Earlywine at Stewart Mcdonald has articals on useing basicly super glue as a finish or on touch up work. The only thing with using it is DO not git it on you and make sure there is good ventilation, the fumes are harmfull as well not to mention burns your eyes and has an awfull smell. I belive it is some kind of cancer causing thing. I would also say that the superglue would crack up or check after some time.
