I would just go get it done by a fiberglass guy. You can go through a dealer or just ask around. They can match any color or shade. You can't see my tower holes that I had fixed, even from the INSIDE. He glassed over using the same color resin and matt, can't see the repair from either side. The outside of my boat is faded a bit, he matched the shade of ivory perfectly. I have to go see him about what my son did with the anchor:(
