1941 international woodie roof question

[David Bruce]

Does anyone know where to get the padding that goes under the vinyl on the roof ?

[Tom Boehm]

I was told by Trimacar who is a retired professional upholsterer on this forum to use cotton quilt batting available at fabric stores. He said it is important to use a natural fiber because man made material such as foam will deteriorate in the heat and sun. I have purchased the padding but have not used it yet. This material is thin, about 1/16" to 1/8" thick. I got enough to do two layers in case one layer is not smooth enough. Also he said to put on a smooth attractive fabric of your choice of color down first then put the padding then the vinyl coated outer roof fabric. The first layer of fabric is what you will see in the inside of the car through the slats instead of the padding.
