Isenglass and Strataglass are optically identical. So the statements of the clarity differences are a little confusing. When we have pieces mixed up in the shop, we find an obscure corner and scratch it with a fingenail to tell the difference. Strataglass resist the scratch. Strataglass best quality is it's ability to resist weather(graying-yellowing). There is another choice that will blow you away in clarity. Makralon is a semi rigid material with clarity you notice right away. I thought it was simply because it does not wrinkle. But I have Makralon in the front panels of my dodger and Strataglass in the removable side windows( chosen for the flexibility). When you have the two right next to each other, you notice the lack of graininess in the Makralon. Makralon is a Bayer product and is the material that drinking water bottles are made of. One warning. If you can get your hands on it in Australia, be sure that the canvas shop you use has experience sewing it.And oh yes, it's pricey. One other thing I have found. When I sailed my boat from San Pedro California to La Paz Mexico, I noticed that the salt spray seems to just flush away off of the Makralon, but the strataglass needed the flushing water and my wet bare hand to knock it loose. Don't ask me to explain.
