I use a lot of shellac for scrolled projects. You can get it in spray cans, but I like to spray it with my compressor and HVLP conversion guns. It's easy to spray, dries very fast and the odor doesn't linger like lacquer or oil finishes. Spray a very light cut and you can hit it several times, from multiple angles to reach into all the frets without it building up. You can mix your own from flakes and get a pretty good variety of shades from clear to very dark amber. You can also mix in dyes to get an even fuller range of colors.
