Pretty sure you want to seal it up tho. Even if damage is not a ride killer. If water gets inside it's my understanding rot will spread.
Two pieces of thin plywood or such and a C clamp or two, epoxy the open areas around the edges, clamp it up between the pieces of wood n trim. I had some topsheet peels on my Arbor requiring similar treatment. Seems to be holding up well.
