While routing out the recess for the maple inlay on the top of my wooden gun case I ended up with a very small imperfection in the walnut that I will need to fill after gluing the inlay in place. I think mixing some fine walnut sanding dust with epoxy will give the least noticable fix. How much sanding dust does one need to mix with the epoxy? Do you want to mix it to a paste-like cosistancy like you would do when using regular wood glue and dust or just enough dust to color the epoxy? Thanks.
