What is Hydrophane? What does it contain? Is it reversible, especially after driving it into the leather using heat? What are the long-term effects of using Hyrdophane on historic leather? Apparently it is a refatting agent for leather that is in use, similar to Lexol or other Neats foot oil or Lard oil products. I would not recommend such products for treatment of aged, hard, museum quality historic leather artifacts.
