I sprayed nitrocellulose lacquer to finish the instrument. I like the look of lacquer, especially on highly figured wood. The lacquer took awhile to build (something like 6-8 coats.) The total number of coats was in excess of 20.
Here are pictures of the rim, resonator, and neck at the end of the lacquering stage. Now they have to sit for 3-4 weeks before buffing and then assembly.
