I have a dilemma. Working from inside my Pearson 323, I managed to drill through the gelcoat into the cockpit area. The hole is tiny really because I was using a very tiny drill bit. Nonetheless, I want to "repair" the hole. What should I use to repair it? I don''t want anything "flexible" like silicone and would really like to match color (although difficult because the boat is so old) for cosmetic reasons. It''s the only through-hole in the cockpit and is in a place where passengers'' backs would be when seated. In the alternative - any ideas for simply covering it up if I am stuck with the silicone option? THANKS!
