For that seriously ugly port light wood, either replace the whole piece or
mix some pl premium polyurethane

Lay a piece of plastic like a cereal bag on top of the patch and press it down flat and it will contour form to the surface and you wont need to do so much fairing.
Was this post for me? I won't use Bondo on a car much less a boat....
