dont you just love these sellers that list stabilized cocobolo,Bacote and such????? Those are the ones to beware of...... these woods need nothing but a good sanding and I polish them just like a silver or gold ring.
Real porous non oily woods need some type of sealer and the vacuum and various plastics and resins do the trick...The vacuum sucks it right into the wood and makes it so to speak water and weather proof.
