Here is how I final polish raw wood on necks.
It has been polished with 2000 wet/dry and the next step is to wipe it down with Naphtha.
Next mix the boiled linseed oil with equal parts of thinner. I use one small Dixie Cup of each.
I wipe the mixed solution on with my hands and then rub it in until my hand can no longer stand the heat of the friction.
Here it is after I have rubbed it in. There is no finish on the surface nor should there be. Once the oil stops soaking into the surface it will be ready to get its final buff on the polishing arbor. This is an exceptionally beautiful neck.
