In the boat repair business, epoxy resins adhere to fiberglass resins a lot better than polyester resins. Epoxy much stronger and polyester will not adhere well for future repair.

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.

You are correct. There are several kits that have resins with various color gelcoat to mix and match for these small holes. Heck, if your going to recoat the entire surface (only way to match this light beigh/almond box) fill the holes with JB weld.
Many large boat and yacht manufacturers have stopped using gelcoat in lieu of 2 part polyurethanes like Awlgrip and Imron

I'll be interested to see how the "white" looks on your box and if it has what I think is an almond tint.

The front of my box is definitely not white. The top is white gelcoat, the back next to trailer is white gelcoat. The popcorn finish on front and sides does have an almond tint. My box is one year old and came that way. Why? No clue. Looks like a screw up, matches nothing. I am easy, the popcorn will stay until I am bored, then poof gone and refinished.
