I'm almost done stitching the hull of my S&G Night Heron, and will be gluing the inner hull seams next. Since I'm staining the panels in black, I don't like the idea of having browinish seam lines (even though nobody will ever see them but me) so I'm thinking of mixing the epoxy and wood flour for the seams with either graphite or toner.

Does anybody have any preference between one or the other ? I've never used either one before, so I'm not familiar with their properties. If I use graphite, will the inside fiberglass cloth be able to adhere to the seams with no problem ? What about toner ?

Regards,

Hugo
