Re: applying bore oil

(Disclaimer - I make and sell a plant derived oil mixture - Bore Doctor and Fret Doctor and genuine Grenadilla Oil).

I feel that the bore wood should not be sealed and allowed to "breathe" because over time the sealant may be washed or abraded away leaving an area prone to greater water absorption and therefore greater hydrostatic pressure in that area which can make the wood more prone to uneven stresses and cracking.

The source of the "Old Wife's Tale" about oil not penetrating probably comes from using the wrong kind of oil !!!

The proof that certain kinds of oil will penetrate Grenadilla wood is an experiment that I performed several years ago. A ten centimeter square stick of Grenadilla wood was coated with oil that had been tagged with a fluorescent marker then allowed to stand overnight at room temperature. Ultra thin (a few microns) slices of wood from the middle of the stick were made with a medical microtome (a device to make slices of tissue for microscopic pathological examination) with diamond blade. These slices were examined using a fluorescent microscope with ultra violet light illumination. The results of this examination showed that fluorescent oil penetrated at least 30 mm into the granadilla wood - see photomicrograph (the red dot is the surface of the wood and the blue staining is the labeled oil, the brown is the wood structure). So, IMO, certain types of oils can penetrate Grenadilla wood deeply.
