I really appreciate the tips, but I was too nervous to veer from my book, that and I couldn't find what I thought would work as a decent filler. I moved forward with epoxy \ resin, mixed with cedar dust, cotton fibers, and silica. I filled in the gaps at the stems, and some spaces in the cedar, last night. I was very nervous to look at it this morning, but I am very happy with the result. I guess we'll see how happy I am, after tonight - when I go to do more sanding. I will be applying a filler coat, before I fiberglass, so I didn't think it would matter if some of the dried material was left on the cedar. I'll be putting it right back on anyways. I don't know - so far so good, I think. ; )
