Pete,
to my limited knowledge Ballistic Nylon comes as fiber weave, not a film type material. There are UV protection films, or dent proof films to be applied on car paint to resist denting from small pebbles and gravel. Also glass anti burglary films do a great job for UV protection, dent and abrasion resistance, but they are heavy depending on the degree of protection needed. Check out Oracal special films, or Llumar.
