At last year's Tx.Assn.Museums mtg. there was an excellent presentation
by Tx. Parks and Wildlife about their use of fiberglass imbeded vinal
graphics (sorry, correct terminology excapes me at the moment).  try
emailing TAM at [log in to unmask] and get info on people/how to contact from
them.  The presenters raved about it withstanding vandalism, direct
sunlight, high heat, temp expremes, etc.  Maybe it'll work for you.
Good luck.
