If it’s not fiberglass I would use the $1000 or $3,000 that it would cost to fix it and buy electronics. Crazy as it may seem I have had great results with scratch repair by getting Oriley Auto Parts to match the color and mix up a one stage urethane. I have an older boat and it worked perfectly. I bought a card of 30 different metal flakes at Hobby Lobby and was able to match the flakes in the paint . Just blew a few on the wet paint. After it dried I wet sanded with 1500 grit. All for less than $50.00
