Mule resonator guitars use them on the neck and I have seen videos from a Canadian luthier using it on his necks. The effect on Mule guitars is quite impressive visually and the neck feels very smooth (although that is obviously more than just the finish).

I haven't found examples of people using it beyond the necks, although I assume that you must also be able to use it on the back/sides if not also the top.

I've been using Osmo Poly-x for necks with great results.

To the OP:

Check out my fairly recent mahogany size 0 in the AGF topic:

Tru-oil is a good treatment for inexperianced users, but I'd advise against it because it takes WAY too many coats to achieve a build up, and it isn't as protective as I'd advise.

I've been using Minwax satin wipe-on poly (NOT the water-based type!!!) for years and have finished many instruments with it. I make up my own "fads" from soft lint-free cotton and apply 3 coats over 24 hours. I'll post a bass building topic that outlines the process. I used the same finish on over a hundred custom lap steels and the results were always quite good.

Here's a bass construction topic on Talkbass outlining the process with photo and text #110:

Here's the text from that topic post:

110. The body components get another of my favorite treatments, Minwax Wipe-on Satin Poly applied with a soft cotton "fad". For those unfamiliar with the term "fad", it is the common name for the pad that is used to apply the finish when "french polishing". I make them by wrapping a small wadded-up ball of cotton fabric with a smooth layer of the same fabric and tieing up the top with a rubber band. A lint-free soft cotton material is best; I like to use old worn-out tee shirts. I make up a fresh fad for each application and try to be meticulous about applying it in a clean and dust-free method, to the extreme of taking a shower and donning clean clothes before a new coat of finish is applied. An ounce of prevention is worth two or three pounds of cure when it comes to finish application. I do three coats with a day between applications and knock down any dust specks on the surface with 0000 steel wool before the next coat. A wipe-down with a tack cloth proceeds any finish being applied, obviously. When finish is done it's time to once again re-assemble everything and finish up by attending to the wiring details.
