I'm thinking of doing shellac for a finish on a maple neck & fretboard. I'd like to use amber shellac, but since it's maple and I don't want it blotchy, should I use non-amber shellac for the first coat, and then use amber shellac for subsequent coats? How many coats are needed for an adequate finish? I do realize that alcohol will definitely affect the finish, but I'm ok with that since I don't plan on spilling beers, etc. on the neck. Also, how tricky is it going to be to use a brush or soft cloth to apply it on the fretboard?
