Now Cocobolo is oily, gluing is tricky as the surfaces have to be oil free to get them to adhere properly. Anyone who has worked with it knows it requires a little more patience, maybe some epoxy and some six inch nails to keeps it in place.

What would you guys recommend for a finish given its oily nature? I am a big fan of French polishing with shellac, happy to use oil and don't have great skills in the spray department for polys and the like. The wood looks its best when just sanded, before the oils seep to the top, it has a rainbow of hues, pink, purples and greens (almost).
In an ideal world I would sand , fill, sand and then get to work with shellac before the oils got to the surface and darkened it. I fear that this wouldn't be the case and that the oils will still come up and ruin the finish.
I wonder whether the safest bet is just to coat the darkened wood with some spray lacquer!
The benefit of your experience would be very welcomed.
