I've done the following. Buffed or burnished to be more correct with Platin Abrasive or similar 'Wet/Dry' paper/Abrasive. Tried that with progressively higher grit discs and a bit more oil.
I also played around with buffing a Wax coat or two on top of a dried Surfix finish.
That came out really nice on a couple of pieces made from Afromosia, which is a bit oily of a wood in itself.
