Especially if all the holes overlap.
Remember it didn't happen overnight. Balsa core that has it's end grain covered in polyester reain as it is bonded to the deck and liner doesn't absorb water easily and will not give it up very easily either.
If you put a piece of wood in water end grain first it will absorb water easily. Now seal the end grain with epoxy or polyester and try the same thing. Very little is absorbed other than by the end grain of any wood and if it isn't going in easily, which takes years inside a deck, it isn't coming out easily either.
