Oratex claims built-in UV protection, but we all know that a finished plane covered with Oratex show light thru it similar to the old tissue and balsa models I made as a kid (slight exaggeration here). How can their "built-in" UV protection be much good with that much light transmissibility? Polyfiber is well proven for about 20 year+ life. Oratex hasn't proved much beyond a few years, so in my opinion the jury will still be out for quite a few years to come. FWIW
