Can ceramic cloth take the heat? If the underlying wrap was Kevlar, with spaced wrinkles for expansion or contraction, then it wouldn't be subject to aerodynamic heating, and the outer ceramic cloth would attach to it. What is the max temperature of the external surface? Just out of curiousity, what is your actual job, as in what NASA equipment are you responsible for or working on. It would be an amazing coincidence if I offered suggestions via telephone and you are actually working on the tank. What kind of fix are they talking about, a different kind of adhesive?
