I'm trying to follow Gary Bruch's "Molding & Casting Fish" article in Breakthrough issue 85 but am not certain I'm using the gelcoat right. The stuff I bought (Marine Evercoat) is pretty thin. I added about 12 drops of catalyst for the few ozs of gelcoat and poured it into the mold but it never completely hardened, even overnight. Also, I'm not sure if this is supposed be set up before proceeding with adding the fiberglass chop and resin to strengthen the body. The article mentions gelcoat can be made thickening resin with cabosil. This sounds cheaper than gelcoat itself. Did I just not add enough catalyst to the gelcoat or is the Marine Evercoat the wrong stuff. Was almost $70 a qt thru O'Reilly's. Any help is appreciated.
