I'm trying to match finishes with the woods. For burls and punky woods, I put a coat of thin CA to set the surface and close any inclusions, then follow it with Optima water-borne lacquer topped with Trade Secret for Wood (TM). For oily woods like cocobolo, Brazilian rosewood, ebony and olive wood, I use a friction finish or shellac (I prefer shellac) followed by a top coat of TSW. For most others, I use Optima followed by a top coat of TSW. For 24kt finished parts, I coat them with Renaissance Wax to add some durability, although I'm starting to powder coat the parts.
