Scooter plastics are not difficult to repair, they just take a little time. They can be repaired like new with only a little work. I use Sure Seal Plastic Surgery resin & mat to glue the pieces back in place, maybe a little Bondo filler on the front face to smooth the cracks. Then prime and paint. You can get matching paint color mixed in a 16oz spray can, mixed by specialty auto paint suppliers. Clear coat if required to match. Time to repair a totally smashed up panel: maybe 5 hours. The repairs are strong and last for years.
