Kampingkris,
Well, I personally have not had it done but, I've seen it up close and have talked with the company here in San Diego that applies it. If we had our previous coach, a '99 Fleetwood Bounder 34V and, were planning on keeping it for a real long time and, the rubber roof was in need of serious repair or, replacement, I'd have that sprayed on roof applied in a heartbeat.
While in San Diego RV Center, I had to have some body work done because someone moved my house while I was backing into the RV parking spot, alongside the house. So, while there, I noticed that they applied that roof coating. I was lead to an area where, there were at least 6, big name, high dollar coaches, waiting for that roof coating to be done. And, there were 3 already coated. These coaches were also, high dollar.
One was a Tiffen, one, a Fleetwood Providence, and the third, a very nice looking Allegro. If I recall, all of them had full body paint. But the roof coating was silver and, lapped over the edge by a few inches, on each one. I asked about having the color of the coach applied on the radius of the roofs and he (one of the service writers there at San Diego RV Center) stated they can do a color match if requested for around, $1,200. Now, I forgot what his quote was for getting any particular roof done.
Most that have rubber roofs, whether TPO or, the regular EDPM types, are fairly satisfied with them. Most that have Fiberglass are also happy with those. I've had solid sheet aluminum too and, that's a seriously strong and durable roof too. But, again, if I needed a roof and, it was within my reach, for a whole pile of reasons, I'd do it. It's a preference thing.
