I have made my first mold of a fish. I used a 22 inch quilback carp sucker I shot last year bowfishing to "test the waters" with. I used the 50/50 Bondo and resin method and then layered it with fiberglass. I touched up the few air pockets and imperfections with apoxie sculpt. Now I need to find gel coat. Where can I get gel coat and pva? If I use mothers carnuba wax on the mold do I still need to spray a layer or 2 of pva on the mold?
