Most violin necks are left raw and polished with finger and hand juice and sweat during use. It gets pretty with time. And nothing takes out the figuring in flame maple better than sweat and hand juice. You can put some oil on it, but it doesnt feel as good as the real stuff.
And you know this because you've worked in several top level violin shops? [:D][:D][:D]
The violin shops I worked in sealed the necks with shellac, lacquer or linseed oil. And depending on the aesthetic of the shop they also darkened the wood by oxidizing it with with potassium permanganate or an oil derived paint stain made with burnt umber and or raw sienna.
Actually the flame and figure in wood pops out much better with an oil based finish than with a hand sweat and moisture. I'm doubtful many high level shops leave violin necks totally raw, they rub them with oil and burnish them with a cloth. But of course there's room for interpretation. The second shop I worked in used a light hand applied lacquer to the neck, the first one a bit of linseed oil and some burnishing. On the recent work I've been staining a bit with a water color and using poppy seed oil and then burnishing with a cotton cloth.
The oil from your body is really not a good finish if you want flame and figure to pop, I'm surprised you said that. The way to get flame ot pop is to increase the refractive index, and hand/body oil imbeds dirt into the wood and blocks the light from refracting. Some people like duller more tame looking necks that don't refract much and the hands naturally give a veil of dirty grease to a neck, which is ok. Who wants the neck to out shine the back and top? I don't, but to say the hand oil gives good the best refractive qualities is misleading.
