Durability of either Rhino or Line-X? Let me put it this way.....I had my bed sprayed in my 2001 Dodge the day after I picked it up 2001. It was still in GREAT condition in 2016 when I sold that truck (300,000+ miles). Oh yeah....I owned a construction company the whole time. It was used daily. Yea. That stuff is worth every penny. But, as most readers here are thinking, why would a 2018 roof need replacement? My present SunnyBrook 5th wheel is 20 years old. I just pu a coat of Heng's on it two years ago. Functions great, looks new.
