Talkingcabbage, I have used Zinsser "bullseye" dewaxed shellac in the spray can from Lowe's over cocobolo and Rosewoods then Spar urethane on top.. But now I spray Krystal Dull or Gloss over oily woods, so far no problems, finish is dry in 30 minutes..but best to give it an hour before touching it.
