So, what does gel coat do ? What is its intended purpose ?
As said, color (including white), UV protection, gloss, and blister resistance, where serious blisters can lead to delamination of the structural layers of fiberglass. Gelcoat is the first layer to be applied in the mold (after mold-release wax). The next resin/mat layer is timed to achieve maximum bonding with the gelcoat.

My own observation is that gelcoat differs from most paints in a significant way: Gelcoat is a relatively soft material that can be compounded to remove its aging surface, and made smooth, where necessary, with fine sandpaper. In general, topside/deck paints are harder, so when they deteriorate, crack, fade etc., compounding or sanding won't yield a smooth surface to overcoat--the paint has to be removed. Not doing so produces repainted surfaces that show the imperfections of the surfaces they're covering. At some point, an older boat might need re-surfacing. A few amateurs are up to the process of applying gelcoat... Most of us would need to decide between having that done professionally or painting the boat ourselves. And many boats are painted professionally with products like Awlgrip and Imron--you'll see that on listings for many expensive used yachts.
