Does anyone remember or know anything about the old decoy molds that you put the foam granules in and baked them in the oven? My grandpa has the duck and the goose mold. I have seen a couple of these decoys and they are virtually indestructible. He used to make them probably 30 years ago or so, they are a very heavy decoy so they wouldnt be practical for the on the move hunter, but would be great for hunting the same spot everday. He told me once that you never worried about shooting the decoys when you shot cripples cause you cant sink em. Does anyone know if you can still get these granules to make them anymore?
