I'm in the middle of rebuilding a 403 and have also started to think about this. As well as the hessian around the tubes in the roof, there is also a lot of felt used where aluminium panels are screwed, bolted or riveted onto steel. Where there is a chance of relative movement, I think it's important to use something to stop vibration and drumming, as well as to stop corrosion. I'm think of using one of the Dynamat products between the superleggera tubes and the roof. However, the hessian was also used to sew the headlining to the tubes, so I'm in two minds. Where felt was originally used, such as under the removeabel floor sections, I am thinking of using felt again, but synthetic felt rather than the old natural materials felt.
