Two of my neighbors in Florida applied what sounds like a similar product although I do not remember the specific brands. One was a 10 year old motor home, the second was a 15 year old fifthwheel with the original roof. In both cases, the prep was critical, a specified chemical wash was required followed by application of a specified primer after which the final product was applied. Motor home was done three years ago, fifth wheel was done two years ago, and both look extremely good. Both owners are happy. No problems like you described. I do remember the product used was expensive, over $125 a gallon. When they arrive in Florida first week in November, I could ask for the specific brands they used, (were not the same) but that wont be much help for your situation. Certainly I would take what the RV tech told you with skepicism about only using on roof less than two years old!?? The products I have read about are designed to extend the life of an aging roof.
