1930 Top Wood Padding to Body?

[dmengel]

I have a 1930 Tudor Sedan and I've read in a few places that there should be some kind of padding between the wood and outer body. When I removed the old wood there were remnants of a felt-like material on the side rails where the top nails in; but nowhere else. Les Andrews' book mentions the need for some kind of material in the forward to the top wood installation instructions but he doesn't show anything in the pictures or mention again in the detailed instructions. Likewise i don't see any reference to this material being sold with or separate from top wood kits. Thirdly I've looked through Brent's outstanding build summaries several times and i don't see any padding going into his cars.

Can someone help identify if the padding is necessary, what type is ok to use and where it should be used? I have constructed all the top wood myself so I don't have a top wood supplier to call.... Thanks!
