I don't want to write a book on gelcoat repair but since this topic has come up many times I'll just make two brief comments.
One: go to a shop the sells FG products where the staff will give you good info and sell you what you need. Marine stores are great but the staff might never have done a gelcoat repair.
Two: The heart of a good and easiest to do gelcoat repair is covering it with vinyl, poly or best of all, sheet acetate, the kind used on old style overhead projectors. Put a drop of gelcoat in the scratch, put acetate sheet on top, smooth upwards moving any trapped air out and tape down.
The acetate will give the surface a glass smooth finish. Sometimes I've left that surface "as is" and sometimes I've wet sanded to blend it in perfectly and then buffed. Old timers called this method "cello finishing".
Works super well and after the first couple of scratches you can do it pretty quickly.
