Marc,
Gel coats are made by many different manufactures, just as fiberglass resin. I've been buying my products from
Merton's in Springfield,MA. They happen to sell Ferro's brand of Gel coat. Gel coat is not a company, it's a type of resin. Awlgrip is a paint made by US Paint.
I tried to duplicate the color F.L.Y by mixing colored pigments to white gelcoat. Just as you would if you were trying to match your existing hull color. You can buy premixed (colored) gelcoat from some distributors.
