I heard about Rhino's Eco-Coat about 2-3 years ago, with the same page mentioned, and the same video... after that, nothing. I've yet to read someone having their rig done with that or any shops offering that application service.
Epoxy elastomer roofs just make sense. I have seen many products which dry... but there is a big difference between that and a two epoxy which cures (different chemical reaction) and cures into something highly stable and resistant to whatever the road throws at it. Plus, it gets rid of the need to caulk every 3-6 months.
When devices like marine buoys or flight data recorders are made, part of their construction is using epoxy resin, or an epoxy resin composite. This only makes sense for the roof.
