question about fish fill. I use Tom sextons WFF fish filler. Is there anything that I can add to it like a 50/50 mix to make it a little more firm and less likely to break away. I mix it to the consistnacy of clay and do not want to mix it to wet. When filling the fish I want tomethinf that sticks together a little better. I am new at taxidermy and I have tried looking on the forum to see if anyone has posted about this but could not find it.
