I have a new boat that i just got a small scratch on the hull mabe 2 inches long from a screw when i was puttting my boat away. I can see a little blue in the scratch i think that might be fiber glass I dont know. I dont no if i should put gelcoat on my brand new boat. My buddy said not to put gelcoat and that it would make my boat slower in the water. How should i fix it. I dont want to mess with the hull to much. I need help fast.
