You could be correct about why it isn't in common use, or it could be that there are some issues with it when used on RV exteriors. It may yellow over time when exposed to direct sunlight for extended periods, or it may crack or craze under the same circumstances, I dunno. It sure sounds good though.
Keep us updated on how it performs. I would love to find something that will protect the decals from peeling. Seems to me the smartest thing to do would have been to put a layer of clear coat over them at the factory.
