I agree. My first choice for a relatively small amount of surface damage or minor underlying damage is to repair using polyester and then top coat with polyester gelcoat making for an invisible repair.
I don't like seeing folks try to do the repair using a colored epoxy only hoping that it will match the surrounding gelcoat. And using epoxy in the "hole" and top coating with gelcoat isn't the best way to go.
And I've mentioned may times in the past using a very old process "cello finishing" can result in an almost perfect repair requiring only the most minor amount of blending in to make a perfectly invisible repair.
