Just noticed this post, I used epoxy only for the bond to the old glass skin. I thickened it with cabosil and troweled it on with a notched spreader and bonded it in place. Quantity used was less than a gallon for that part. The core had 2 layers of Matt applied to it on the bench to fully sill it up before I bonded it to the hull. I also laid strips of matt at the base of the core to bed it in to the bottom of the hull. In between the plys I used 2 layers of Matt then 2 layers of thick roven with Matt stitched to the rear. (Simular to 1708) then 2 more layers of Matt. I used the roven due to It was free gIven to me, 1708 would be slightly stronger but I wanted to use the roven/Matt up. The Matt holds a lot of resin to fill voids and for the wood to soak up. Make sure the wood is pre coated with resin a few times before the layup. I use thin vocosiy resin so standard resin you might want to thin it so it will soak into the wood better. On the outter layers I would start with the Matt then several layers of 1708 after that. Also I filled any voids around the edges and bottom with a thickened paste to avoid air pockets before I started on the outter layers. I added lots of extra tabbing to the hull sides with each one slightly larger overlapping the last. I would say but not sure it took around 3 to 4 gallons maybe close to 5 time I filled the stringers back in.
Maybe this will help you out, I know you have got passed most of these points. Sorry to be late on the reply.
