1. Find professional repair services: You can find professional car repair service centers, which can provide repair and replacement services for the grille. They'll assess the extent of the crack and apply the appropriate repair method, such as filling, reshaping, or replacing the grille, depending on the situation.

  2. Use car repair glue: For smaller cracks, you can try to use special glue suitable for plastic or car repair. Clean and treat the cracked area first, then follow the glue instructions.

  3. Replace the grille: If the cracks are serious or the repair effect is poor, you need to consider replacing the grille. SHINESELL AUTO recommends contacting a car dealer or a professional auto parts supplier to purchase a new grille that matches the model and have it replaced by a professional technician.
