I got a scrape in the gelcoat on the edge of my bassboat. It is not real deep or large about the thickness of a dime and size of a half of a dime in circumference. it took the clear layer off down to the shiny flecks underneath. It is located on a slanted part. Is there some type of clear liquid I could put in the scrape. I was thinking of clear nail polish? It would have to be a thick clear liquid that would harden quickly or it would just run down the side of the boat before drying. I don't want to buy an expensive kit or something just to repair one scrape. Any ideas would be greatly appreciated. Thanks.

 

P.S. this happened due to an idiot at the ramp with a giant yacht who didn't back his trailer far enough into the water. He did not want his Hummer truck tires to get wet, Instead he gunned his engine and tried to drive the Queen Mary  up onto his trailer. All of the boats tied to the dock, including mine were tossed violently in his wake. We yelled to him and he laughed and drove off. What a tool!

Anyone repaired a small scrape or chip in gelcoat?  Any good ideas?
