A am trying to pour some fishing lures and they need to float. I tried some smoothcast 300 today and the stuff worked perfectly except it sinks like a rock! I read at smoothon that you can add "microballons" but I have heard it's hard to keep them from floating to the top of the mold while the stuff is curing. Does anyone have experience using SC with microballoons or know of a product that will work for me?
Thank you!!!
