    If the part requires UV resistance, it should have gel coat or quality paint over it.

    What are you expectations of this coating?


    Pigmented epoxy is a poor choice for just about any purpose, so it's of limited value.

    If I am using carbon fiber in a mold, I might use pigmented first coat in the mold to hide the carbon fiber. Example: rudder. But, I agree with your assessment otherwise.
