I use clear Bullseye. If it feels a bit rough sand it before the next
coat. If you want interesting colors uise white tape and dye the
shellac with cloth dye-powder-or alcohol based ink (available in every
possible color at the art supply store). I never need more than 2 or 3
coats.
And for a really nice look use pigmented shellac on white tape. It
comes out a beautiful cream color that draws admiration where ever you
go.
