We have different rear wing rules for different race series; some only require the wing to be on at the start of the heat, and some race series require that wings have to be re-installed during the green flag heat. Also some race series allow taping the ends of the wings, or reinforcing the wings, and some do not. My comments before were just a statement of fact. Having to replace a wing during a race (unless it is a snap-in wing) means that heat and that race are done for the car. Even if the supplies were ready and available at the driver’s station, it would take a minute or more, and would probably not last. I would rather that a quickie, futile attempt to repair a wing, which might complicate a later, at-home repair, not be attempted.
