Finishing Exotic Woods

I have a question regarding the finishing for Exotic Wood, namely Bloodwood (and later on, Bubinga).

Due to the high oil content in these woods, normal Polyurethanes will not work- virtually never dry.
I have read that De-waxed Shellac is used as a sealer on which you can apply Poly or another finish, or just use Shellac like in a French Polish.("Shellac sticks to everything and everything sticks to shellac")
So, I have the De-waxed Shellac flakes, the denatured alcohol and am ready to mix my own Shellac.
The question I have is this: Do I wipe down the Bloodwood with acetone (and let it dry) before wiping on the Shellac or can I just apply the Shellac right on natural Bloodwood surface?
I plan on running some experiments on scrap pieces of Bloodwood from my current dulcimer project, but would love some ideas from friends here.
Thanks for any help on this one!
