My new to me 1957 Skyliner will be arriving at our home, sometime in the next few weeks. My car has a simple painted finish on the inside of the trunk lid. I have seen what appears to be a black colored material on restored Skyliners, inside the trunk lid. Would that be the bumpy felt material that car makers commonly used on the inside of the sheet metal, behind the upholstery. I ask this because I have a whole roll of it in my garage.
