I would contact Interlux. They have tech help available. I would not use Perfection below the water and the VP is specificall designed to be below the water.
The barrier coat is also designed to be below the water.
UV may adversely affect those two if used where they are not designed for.

There are also many 1 part paints made by Interlux that will do what you want and be less expensive and easier to use.
