Finishing a fiberglass repair

[trents99]

I had a repair hole about 4'' x 20'' on the chine I believe it's called; center v-shape running down the center of the hull right up to the transom on my tri-hull. I have layered about 10 layers of CSM and heavy roving for structure but the chine didn't take the original form as well as I hoped. I assume the boat will not handle at all under throttle until this is fixed so what product do I need to use to reshape the chine?

Also what do I need to use as a top coat/sealer? Not concerned with how it looks because it will get new paint eventually. Just want it water proof so I don't have to fix it again.

thanks

Sounds like you have it somewhat close to
the original shape. The shaping process you are referring
to would be "Fairing". I personally used West Marine Products
but there are several out there. It's basically a powder figerglass
material you mix with the epoxy in different thicknesses as needed.
Lots of sanding.Very simulair to working with sheetrock mud in application.
There are several steps,did I say lots of sanding? The last steps will be
spraying gel coat. high speed buffer w/ rubbing compound, polish,wax,etc.
If I can do it anybody can.
