A similar product was used to paint the Hindenburg and it is now believed by
many (but not all) that it was this that destroyed it. The film of the
flames looks 'wrong' for a hydrogen fire. A sample of the skin, which had
been saved for many years, was subjected to a spark test and burned with
great enthusiasm.
