My rubber roof is 20 years old. At about 12 years old a friend bought a new MH with a FG roof and gave me a gal of Koolseal and a gal of primer. I used it because he gave it to me. I had enough for one coat. It looked great for 4 years and it began to slough off. My roof looked like yours and based on my experience I would wait until the black starts to show through the white surface before you coat it. As another data point another friend has a 20 year old Bounder and his roof it totally black the white has all sloughed off but it still doesn't leak. Coating the roof will reflect the sun reducing the inside temps in the summer. Also it becomes the sacrificial coat that will wear preserving your original roof.
Interesting point of view..... So essentially the "white" part is only a protective sacrificial material over the "black" rubber material underneath.....also aiding in reducing radiant heat? So therefore, as long as the black material isnt compromised then its all good? I've never heard anyone ever explain it like that. :)
I agree with Gjac, and that is my point of view also. I will add to it some.
I would not do anything until the roof was 15-20 years old (depending on where you are located, down south - 15 years, up north 20.) What you will see is a crazing of the rubber roof. Fine spider cracks everywhere. The coating will fill those cracks and not allow water to sit in them.
If you do use something make sure it can handle what is known as "puddling." Most can not, the paint will dissolved if there is a puddle of standing water. These are normally the very areas that will leak on a roof.
