Had some damage to my gelcoat last year from a loose cover/snaps flapping during trailering, bought a quart of gelcoat material and fixed it myself. Takes a bit of time with proper prep/curing and finishing, not rocket science.
Do a internet search for your gelcoat color if you think you care to try it. I used Sea Hawk brand.
Dixie Marine in Fairfield did some repair work on my Ranger last winter, could not tell that there was every anything done, and I had quite a repair done to the "sparkley" part of one of the main stripes and the pin stripe.
