go to a boat dealership or a boat repair place and you can fix this with a fiberglass repair kit.
You have your directions, your two part chemicals, hardner and glue or fiberglass and you have your cloth.
this will sand down and paint and look just like new.
I have repaired many of fiberglass holes in my sailboat this way and it is stronger than the surrounding parts. Sand it down and paint it and walla.
Use all safety precautions when working with this product as fiberglass is not good for the face and hands area.
