Hi there! Sorry to hear about your car. It's always tough when something like that happens. In terms of fixing the damage to your rear bumper cover, I would recommend taking it to a professional to get their opinion on what would be the best course of action. Depending on the extent of the damage, it may be possible to glue or epoxy the loose flaps and missing chip back into place. However, it's important to make sure that the repairs are done properly and that the bumper cover is weatherproofed to prevent any future issues. If you're unsure about how to do this, it's always better to err on the side of caution and take it to a professional. They'll be able to assess the damage and give you a better idea of what needs to be done to fix it. Good luck with everything!
