Polyurea (truck bed liner) was so far the second best, but you could start seeing some decay after on the first year.

Roofing coatings like Dicor, or the ones you can buy specifically for EPDM or TPO started to show a little bit of aging on the first year (dry spots, flaking, etc).
I have become familiar with the life cycle of roof coatings on RVs, having done so many for my rental business. At the 1 year mark you can see what the lifespan will be.
So far, under the florida sun everyday, still no problems.
The roof in my Alfa came out great. As far as the application, it is a 2 step process, so a little more work. As far as cost, is in the middle of the road.
Hope it helps.
