What has been your experience with the smell?

By contrast, I spent 15 minutes with a rep from Oddies Oil, a product with almost no smell and zero VOC, one that one can eat. (I suspect, based on the smell, that it is at least partially neem oil.) I've since used Oddies Oil on a few cutting boards and a writing desk. Easy, easy, easy to apply, no odour, won't water mark after fully cured in a few weeks. One uses minuscule amounts of the oil, unlike typical penetrating oil finishes. I've not tried it on guitars, but it could be a viable finish, depending on what appearance one wants. I think it would be excellent on dulcimers and similar folk instruments. The gloss of the finish is largely dependent upon how finely the underlying wood is sanded and will produce a nice lustre, but not a high gloss. Probably won't work well over filled pores.
Your reaction to the smell of the Osmo product are very interesting. I don't know about their full product line but I found the Osmo Poly-X to have a very low odor intensity and what was detectable was unusual, but pleasant.

I know 3 or 4 other small shop builders who have had the same positive experience with the Poly-X satin product.

I've also used Rubio Monocoat (the same class of product) and it did have a slightly stronger smell, but not what I would consider objectionable. The Osmo "cured" faster than the Rubio product and the residual odor disappeared within 24 hours of application.

I've read other positive reviews of Oddie's Oil and may try it in the future, but the Osmo Poly-X really satisfies my requirements.

I'm always on the lookout for a protective finish for necks that satisfied the requirements of sealing & protection without any residual grab or stickiness and the Osmo Poly-X does that for me.

This stuff is EXPENSIVE, but worth the price. It's available in small cans, but it goes a long way. The exact formula I'm using is "Osmo PolyX Oil High Solid #3054 Clear Satin for wood floors and furniture".

These "hard oil" products are unusual in the sense that you can't "build" a finish. The Rubio Monocoat instructions plainly state that it is impossible to add a second coat. Anything beyond the initial coat will not bond to a previous coat, so you simply waste product by attempting to apply additional coats. When they say "monocoat" they mean it.

The Osmo PolyX instructions call for 2 coats, and that seemed to be the optimum in my case.
