Also - After some experimenting . . . I was able to match the white gelcoat color. You can see a few shades of white in the repair . . . but if you look inside the red square . . . you can see the color match. It's a white base gelcoat with a little bit of halyard white pigment. I try to quantify the "little bit" in my next batch. I think it amounted to roughly 1 teaspoon
I just started with a few drops in a quart and kept adding samples on top of an existing piece until I had a close match. Took a few tries, but I think I got it with the color in the red square.
