Ahmet - my approach to making flat pieces is to first laminate on a sheet of
glass. With polyester, I build-up glass/mat alternating and laminated to a high
glass content with a consolidator. (A kind of roller)
With epoxy you can use biaxial stitch-mat with fine cloth or peel ply on top,
then squeegee out resin. Use a layer of waxed paper between the glass (or
Mdf) as a release layer.
If cured on the glass you can make amazing sheet parts, and assemble them with
with fillets of epoxy.
You can also do the work above on a sheet of waxed paper and apply the
resulting laminate before it kicks. You basically make a band-aid and plop it
in place. (Essentially)Much easier and better than laminating in situ. You
can take these laminates and lay on a form, pre cure.
By progressively sizing the pieces, you can make band aids thicker in the
middle, often useful.
In your case, if I understand correctly, I would combine both pre made pieces
and pre laminated 'band aids).
I would fill the void with glass-rich epoxy. If you need it to flow and level,
use only a little cabosil.
You can get a veterinary syringe or make a piping bag out of a ziplock if you
need to inject into a space.
Consider laying cloth on its bias for corners bridging seams. Remember to
feather edges to maximize gluing.
Dave.

Thank You, that is a lot of information condensed.
I have a challenge. Whoever built my hull # 5, missed the sump location by
an inch. So I need to extend the sump wall horizontally.
I would thing that I would start wetting structural mat and go horizontally
out from where the exposed nut is. It is basically a 4 inch vertical wall
than needs to be filled in.
The situation is in PIC 3 <http://www.boatjuggler.com/images/pic3.jpg>
Here is sort of a drawing <http://www.boatjuggler.com/images/Drawing.jpg>I
have.
What might be the best way to build up the vertical wall that will
eventually withstand the pressure of the nut besides just keep on adding
cloth until I have the desired width ?
