Drawing from my past experience of working in a boat factory, I will tell you what I know about gel coat.
First, there is a "mold" for everything fiberglass that I'm aware of.
They wax that mold inside so the part doesn't stick to it when they remove it.
Then the part we see. Like your front cap is sprayed into the mold. It's referred to as gel coat. They can put any color they want or need into the gel coat. In the instances of the fading front cap, it was a brownish pigment that was added. After that dries they will add the fiber glass cloth and then depending on what is needed for strength, they will spray in the fiberglass matte. When everything has went thru the curing process and time, it's popped out of the mold and the process starts all over again.
I hope the process now is the same as it was back when I worked in it.
