It is time to do the covering on the Radial Cowl Thunderbird I am repairing. Originally it was silk covered. It has had one recovering using tissue. Both silk and tissue get brittle with age and eventually develop cracks. Since the model will be going to Woburn Abbey for permanent display I would like to produce a finish which will last for ever! A really durable and strong authentic looking finish can be produced these days with tissue over mylar. It may not be totally original, but for longevity and this totally original look, I am considering silk on mylar. Anyone have any thoughts on this?

IMHO If I were doing this project, I would not worry to much about the covering material as much as the paint,, Dope from my experience is what actually gets brittle, not the covering. because of the inherant nature of Laquer materials, they dry continually forever and ever,,. Were I to do this project I would minimize the amounts of dope used and instead use catalyzed products, (car paints) Since this will be on display and not flown, the major concern of those unfamiliar with auto catalyzed products , that being weight build up, is really a non issue,and the Urethanes will last indefinetly when not being exposed.
Just my two cents worth.
