Just like the coated cardboard unit installed at the factory. While in service as a Hertz unit, mine was damaged. Then, the goofballs at the service lane didn't secure ALL the fasteners. My vehicle spent 68 days in the shop chasing a rattle they couldn't find. I discovered quite by accident, the deformed pan and lack of fasteners allowed it to 'bump' and rattle when driving over rough surfaces. New cover fixed it, and BOY AM I HAPPY!
