Exterior components like bumpers and fenders must meet specific impact resistance and paint adhesion standards. For plastic parts (bumpers, grilles), ensure they are made of PP+EPDM-T20, which provides the necessary flexibility and durability. For metal body panels, verify the electrophoretic primer (E-coat) quality, as this is essential for long-term rust prevention. If purchasing LED headlamps for newer Geely models like the Monjaro or Tugella, confirm the CAN-bus compatibility to avoid dashboard error codes.
