The customs and CST came with a factory undercoating for sound deadening purposes. It is about a 1/2 inch thick. Some of it is coming off inside my doors. Any way to replace?

I don't know about factory undercoating, but the 3M stuff works good. The cheaper NAPA generic undercoat also works well. As far as sound reduction, Dynamat makes sheets or spray on sound reduction material.
