Over 6 years ago I hung a couple of strips of the white Oratex that I used, in the back of my house with an unobstructed Southern view. We are at an elevation of about 5700 ft., and Colorado is known for a semi-arid environment and a great number of sunny days/year. So for those 6+ years these strips have been hanging there 24 hours a day, 365 days/ year. I finally got tired of looking at them and took them down. I wish I had tested them each year, but I didn't. Anyway, they are definitely un-airworthy now, and they tear fairly easily... they've taken a real beating! I haven't really proven anything except that it's obviously unwise to keep Oratex (or any fabric covered airplane) outdoors, exposed to the sun & weather for years. Especially in a climate such as here in Colorado. Most who read this are probably thinking, "well duh!"
