Check YouTube for videos on repairing the bubbles. You should probably use the same type glue used for installing the roof.
Last summer I restored the roof on our 96 Southwind. I did not have any bubbles. All seams were covered with Eternabond.
I used Heng's Rubber Roof Coating. It goes on easily, does a nice job and looks good.
Heng's requires no primer. I used a 4" roller to apply the coating. I chose the 4" because I was not in a hurry and had better control.
A brush was used for trimming.
So far it's held up to sun, snow, ice, rain and Pennsylvania's freeze/thaw cycles. No peeling or leaking.
