Finishing Carbon Fiber

I am not building a boat but, I have been building a Fiberglass/Foam/
Carbon Fiber skatebaord decks for a couple of years. I would like to
get a smooth colored exterior surface on my lay-ups. I vacuum bag my
lay ups and this is my normal construction method:

Triaxil Fiber glass
1/16" thick maple core
3/8" last-foam
Triaxial Fiberglass
Carbon Fiber
Colored Cotton Cloth

I used the colored cotton to finish the bottom of the skateboard deck.
After wetting out the cotton cloth and applying over the black carbon
fiber the color of the cotton cloth darkens up. I would like to be
able to get a bright solid color on the bottom of the deck.

Here is a link to a picture of the skateboards I build:

What other options do I have to get this type of finish?

Thanks

The link doesn't work with my browser but I know they make a special
fiberglass that dries perfectly clear. It's for encapsulating
scientific specimens etc. Not cheap. You could hand paint and then
spray coat with that stuff. I don't know how durable it is and I know
the skateboards take maximum abuse.
As you probably know, the colors you mix with epoxy or fiberglass look
awful but I did mix some kind of dry powder pigment with West System
epoxy that came out super vivid. I got it from an oil painter/artist
and I don't know what it's called. You could ask at Daniel Smith or
Dakota etc. Good luck, sounds like a cool project.

I have used water-soluble poster paint powder to tint epoxy to make
tools with color spots. Light colors worked well for me.

It's another type of work, but could you not use undercoat and 2-part
urethane etc?

Interesting layup... anyway, some options are:
- Pigmented resin additives
- Paint (either enamel, 2 part polyurethanes, or spray)
