Get a bicycle inner tube repair kit and an old inner tube. Cut a piece of old inner tube to cover the hole. The glue is. Contact cement so apply a thin layer of vlue to the patch and the hole and the area around it. Wait for the glue to dry to the touch and press the parts together.

You will see indentations on the tray where the metal parts of the top mechanism rest when the top is closed. I pre emptively patched these areas to avoid leaks.
