What is the cause of bubbles shortly after appling epdm on Motor home roof? Will they go away?

I just applied the coating for Motor homes and campers, the flexible type liquid rubber. I have some quite large bubbles that raised up and some winkles in a few places. What causes this? As it is only in some places. Will they ever go down or what do I do for them?

Hi George

Actually that is one of the biggest benefits of the product that is what would otherwise be trapped air being forced to the surface.  Those bubbles will go down as all the catalyst is evaporated

Thank you

Thank You
You are correct, It did go down.
 However it caused two problems.
One....As it stretched into a large bubble, it became much larger than its original area, so it cannot lay in its original area.
Two.. there is NO BOND in this area at all,  I am sure that this area will tear at highway speed and blow off.
I am thinking I may need to carefully remove this area, and apply a contact cement or some bonding agent. Then order more material and recoat this area ??? This roof was not in bad condition prior to coating and was thoroughly cleaned and prepped as direct by phone, by Your company. I have before and after pictures.
Please give me Your advice, as I am waiting for Your reply.
