I am also looking to do something with my roof this year. I did a pretty thorough search of this and 3 other RV forums and wasn't able to find anything. I also did a pretty good search of the Internet and was only able to find information that was supplied by those who stand to profit from it, including Camping World of Dothan, AL.
While the EpoxyFlex system sounds intriguing I think the jury is still out on whether or not it is actually a viable system. I think I'll wait for more info before moving on what is obviously an unknown and unproven system.
