That is a third product that is in that category. There is
Dave's Permanent Coatings with RV FlexArmor and Rhino Linings.
The upsides: Once stuff is sprayed, assuming it is evenly applied and properly prepped, it means no worry about Dicor, no Eternabond, just looking at the roof for any punctures from tree limbs every so often. No more worry about cabover rot, etc. Since rubber roofs seem to have a bad reputation for leaking (all it takes is one imperceptible crack in the Dicor), having a seamless roof goes far.
The downsides: It would be nice to have a fixed place to take rigs to. A/Cs needs replaced, skylight domes crack, people upgrade vent fans, so when that is done, the roof will need a touch-up application to stay watertight.
The biggest downside is that there are no places that do this type of work barring Florida. If Rhino Lining offered this at all the locations they spray truck beds, or if Line-X offered something similar at all the shops, this would cure the biggest cause of an RV destroying itself -- water intrusion and rot.
It is interesting that they offer to come to you... but that might be expensive, and if they are full-timers in another state, where does one go for a touch-up after a replacement of some fixture? I am not intending to bash them, but just curious about these things, as spray-on elastomer roofs would be extremely useful.
