In Oct-2020 I went to the The Reef RV Park at Rocky Point (Puerto Penasco) and asked Carlos and Pablo to clean the roof radius with 92% Rubbing Alcohol... remove the old glue and apply Geocel "ProFlex" Clear sealant to my roof. They did a great job for $200 after tip. (2-days and 8 man-hours of labor, including adding additional screw to my front cap over the driver's window.)
In May-2021 I returned to The Reef and asked Carlos to clean, tape, and brush on Flex Glue Clear right out of the can...and put it on top of the ProFlex sealant for UV protection.
Why? I'm tired of having to do regular roof maintenance to avoid my roofing getting blown off in the wind. That already happened to me 4 years ago and it cost $35,000. Fortunately, my insurance covered it, but only because I keep a "log book" of every repair and every service every preformed to my RV.
MORE INFORMATION
All hybrid and polyurethane sealants break down in 1-2 years when exposed to the sun; and since I'm always driving my roof gets a fair amount of sun.
The outcome of applying Flex Glue Clear (out of the can with a brush) over the ProFlex sealant turned out better than I expected. The Flex Glue Clear is very clear and when you tape and paint this stuff on it looks just like an OEM job after you are done.
So now I have the strength of the ProFlex sealant and the UV protection of the rubber Flex Glue Clear. Is this a better mouse trap? We shall see.
Ask me in 2 years and I will let you know.
What I can tell you is that a 40' RV flexes a lot when driving over ramps to gas stations and the like; and when leveling; and the sun will destroy all the roof sealants over time. This is been the case for 20 years +; so I am hopeful that adding a rubber layer on top of the roof sealant will work. TBD.
