This will give you some indication with Baltic Birch. The one on the bottom is finished by dipping is a mixture of 50/50 BLO and Mineral Spirits. Let it dry for several days than sprayed with "Deft Clear Wood Finish" which is a lacquer. The one on top has no finish because he went blind in the left eye before I finished it.
But you really have to experiment. There are different mixes with BLO, like, BLO/MS/Poly. Different sprays to put over it also, of coarse.
