I can only tell you the one and only experience I had. It was a uv curing varnish for wood. Before using it, I didn't like the curing time for and exterior varnish that needed to be outside to cure for something like 24hrs. Perhaps in areas like Vegas that's fine, for south florida when it can and probably will rain, not so good.
That said, the humidity was low and no rain for days. Still, it didn't hold up well and went back to using Sickens.
