As a former industrial coatings chemist, I can tell you that "easy pour-on" generally also means "almost good." While I have never (yet) coated an RV roof with any of these products, the nature of the beast is such that a clean roof, good surface prep, and smear -- not simple dump the bucket -- technique is at least as important as the product chosen for the job.
I just bought a 4.7 gallon bucket of Henry Tropicool to do my RV roof, a task I'll be undertaking this spring before camping season. @JBarca, I'm all ears for your experience and tips regarding that product.
