I forgot to mention that this particular wood is "Padauk".

I used General Finishes Arm-R-Seal on my Padauk projects. They're inside, so
the natural Orange of the Padauk has remained. I did mave some unfinished
cutoffs that were exposed to direct sunlight - they went to a rich chocolate
brown color. No idea whether Arm-R-Seal would have slowed that darkening or
not.
