I agree with Kim. I haven't used lemon oil, but I frequently use mineral oil to finish my scroll work. I think it does a beautiful job at bringing out the beauty of the wood and is easy to apply and cost effective. I either dip the piece or brush on the oil (depending on the size of the piece) and then I put it on a metal rack (the type you cool cookies on) to soak in for a bit. If there is still oil on the surface after an hour or so, I take a paper towel and wipe the excess. I then leave it to "dry" overnight. In the morning, it is drier to the touch and not greasy feeling. Then I use spray shellac to seal in the oil. I use a couple of coats, allowing to dry in between. Then I glue as needed.
Most of the fretwork and pieces I glue don't take a lot of abuse, so this works out well. I haven't had any bonds let go by using this method, although if they are frequently handled, you may need a different sealer or allow more time for the sealer to dry before gluing.
I hope this helps you out. It works for me and is a fast and inexpensive method to finish your work, as well as give it a beautiful finish. I love the way the shellac looks over the oil. Warm and rich.
Good luck and let us know!
