As cocobolo is a dark wood I'd be leery of adding more colour to it
so....instead of the "usual" BLO (Boiled Linseed Oil), I'd be tempted to see
if you can find a small container of "raw" tung oil. Mix this with
turpentine and a good (spar?) varnish in ratios starting at 1/3, 1/3, 1/3.
Test it. If it's too orange, drop the varnish content and increase the tung
oil. If it's not orange enough, go the other way.
Another finish you may wish to try is simple shellac. With flakes there are
a bunch of "colours" you can mix (blonde to garnet) or if you choose, you
can simply pick up a can of Zinsser Seal Coat from the store and use it.
Thin the first coat 50/50 with denatured alcohol and apply. Let it dry,
scrub off the raised grain with 220. apply a full strength coat, scrub off
the fuzzies again and then start building coats until you get it looking
like you want to.
As for acetone first, I'd probably not bother. True you should do this prior
to gluing, but not finishing as it's redundant (remove oil from the surface
so it will take an oil finish.....?)
Best of luck

no use using acetone on it. You can use a oil and wax. You can use shellac. If
you want to sue a poly type finish use a spit coat of shellac first.

what kinda of poly --water or oil based ? I was thinking of doing poly over
shellac on a recent project, but the poly (yeah it was minwax) said not to
use it over a shellac coating (it was oil poly)

Yeah, 6 or 8 coats so you can get that really neato
plasticky look! (...while the rest of the tree rolls
over in its grave.)
