I have been working on my first fretboard and finally got my inlays glued in. The inlays are celluloid (hand cut from celluloid blank purchased from Rockford Carving (ebay seller partsforguitars) set in a rosewood board. I have level sanded the board with 150, 220, 400, & 600 grit paper. The board feels smooth as glass, but if you look closely at the inlays you can still see slight striations: So my question is, should I keep sanding until these striations disappear? I cannot feel the striations with my fingers. Is there another step to polish the inlays smooth, or should I just keep sanding? On another note, I filled the edges around the cavities with rosewood dust and CA glue. The dust itself was much lighter in color than what can be seen in the pictures, but it seems as though the CA glue (which was clear) made it much darker. Curious to know if I had used clear epoxy if the color would have not turned out so dark.
