Can anyone provide any guidance to me on repairing the photos in the links below? I am no expert at fiberglass work but I have done a few repairs. Do I need to remove all fiberglass in the entire area so it is just an open hole surrounded by intact fiberglass, then repair? Or could I just add glass and resin to fix? It doesn’t need to look nice or be light, just needs to be water tight. I can access the inside via a port hole.
