I've seen a few references to Durham water putty as an alternative to epoxy mixtures for patching gaps. But I can't find it anywhere.

I tried some Elmer's Fill'n'Finish Wood Filler paste, but am not entirely satisfied with the results on some scrap strips. I got the light colored paste, to match the lighter eastern white cedar, figuring I'd darken it up with some WRC wood flour to get a better match for the mid-tone EWC and the darker WRC. It matches OK with the light & mid EWC, but I can't get it dark enough to use with the WRC. It is OK, but I'd like it a little darker. Mind you, this is all on the bare wood. I don't know yet how it will look under epoxy.

Is the Durham putty any different? How dark a mixture can you get with Durham's. Is it available in Canada?

Another question. I have one joint between strips in the mid-tone EWC where the glue line is visible. It looks like it will finish (after epoxy) as a darker line than the surrounding wood, unlike the visible glue lines on the darker WRC hull, which appear lighter than the surrounding wood (I used regular Titebond for all stripping). I am debating whether to attempt to chisel out the glue line and make a patch, or whether the repair would wind up looking worse than the glue line. Any comments??
