: I colored Durham's with aniline dye see the post below.

: The trick I use to filling holes on S&Gs is to mask the outside of the seam
: between stitches and glue between the stitches from the inside with
: loosely thickened epoxy (less than mayo thick but more than honey thick)
: so it flows through the crack to the tape. After cured remove the wires
: and mask the remaining portions of the seam and the holes and complete
: gluing the seam with the loosely thickened epoxy. At the same time make
: the full fillet using a radiused strike-off tool (tongue depressor) and
: let it set until rubbery (a couple hours). Then apply the glass tape with
: unthickened epoxy.

: The holes will fill without wetting the outside plywood and without drips on
: the outsde to sand off. The fillets will be nice and even without the
: finger/brush/spatula dents.

: I thicken the epoxy with fumed silica with only enough wood flour to color
: match the epoxy wetted wood.

That's good info Dave, thanks. My seams are already glued with epoxy and the wires are out but the angle between my hull panels is so shallow that I won't need to be filleting most of them. I'll mask off the ones that do need to be filleted so I don't have to do a lot of scraping afterwards. I have some water based stain that I might mix into the Durhams to darken it a bit before I fill the holes - it is awfully pale by itself but the holes are so small the color doesn't have to be exact to look good.
