: How much gelcoat is needed for a 10 ft. kayak?
: Can gelcoat be put on over epoxy with epoxy pigment in it? ( This would be to try epoxy pigment and if it doesn't work use gelcoat)

probably a quart to 1/2 gallon would be enough.

If you are using epoxy the gel coat can just be pigmented epoxy spread on evenly with no glass.

I would not mix polyester gel coat with epoxy. It may work but I don't see any point in it.
