Chapples

I just created some of my first soft plastic fishing lures, I bought my molds from netcraft and I am pleased. My question is I have the frog mold (Plastic Worm Molds, Make Your Own Soft Plastic Fishing Lures#) its a swim frog, Im not sure if there is something special I have to do with the plastic to make it? Is it suppose to float? or do I just use the #502 liquid plastic I have with color? I also was woundering if anyone else has tried to use acrylic pait for color, I went to walmart and tried this since i forgot to order color and it seemed to work great when mixing it with the soft plastic. The glitter I bought seemed to loose its color tho, maybe it cant withstand the temps? Thanks everyone
