We have rubber seals that have come loose from the clear plastic roof windows/vents on our Creative National caravan (Australian made). The vents/windows are like a curved dome that let in light but open upward to let in air. The inside section has a separate shade and retractable insect net. Any ideas about how to reseal or reattach the rubber seals onto the plastic dome would be appreciated. Do you push the rubber seals into the curved outer sections of the window/vent?
