6 months? Mine show after a week or two.
I like it.
If everything is too flat and shiny, it reminds me of those painted on rosettes on cheap classical guitars. I was pleasantly surprised with an inlay recently, which I used multiple pieces of ebony on, even though it's pretty much pitch black and the pieces touching together could have been done in one large piece. But after the shellac had time to dry, you can see the seams between pieces, and a bit of the grain showing the orientation of each piece. It looks "real"
(because it is)
