I'm building a modified Kidarka for my 7 y/o daughter and the she really wants a green kayak. I've already ordered the nylon from Skinboats, so the next question is how to color it. I'd like to use the Skinboats urethane if possible, but I'm still not sure how well pigments work with it. I called Corey, and he steered my away from dying - to many delam problems. The problem with his pigments is that he does not have green. He recommended adding some acrylic paint, but I've heard several other people talk about adding "artist oils". He also vaguely remembered some problems with cobalt green and his urethane.

Does anyone have any experience using pigments with Corey's Goop, especially green pigment? If so, could you post a photo? Finally, is there any guideline for what kind of pigment to use - something inert and color-stable?
Thanks for the help
