The black korina/limba comes from the same tree as the white limba/korina - although there is another tree thats wood also gets called limba that only produces the white stuff. Its adifferent tree but the wood is identical structurally and tonally..... anyway the point is that black and white limba sound the same.
I have used black limba for bodies a few times, its main appeal is the black (and occasionally orange) streaks that run though it.
The book take you through the danish oil method in more detail but it basically goes like this.
1. Sand to about 400 grit
2. Heavy coat of oil - leave for a while and buff of the excess - leave over night
3. get some 400 grit wet and dry paper and wet-sand the guitar with the oil. Buff of the excess and feel how smooooooth it is.
4. Repeat this a few times going up to 800-1000 grit wet and dry paper.
5 . buff off all the gunk and leave overnight
6. apply wax with 0000 wire wool, really rub it in then buff it off.
7. Repeat till happy - keep going and you can get it up to quite a nice semi-gloss and you can always add more if you decide it needs it
