  1. Here's the response I got from Smooth On. I guess foam is out. Are there any other alternative materials for casting hard baits? --------------------------------------- Thank you for your inquiry. Flame out foam will not burn, however Urethane foams are not high heat deflection materials. The symptoms you have described are typical. Usually about 150 F max is all you can expect out of a Urethane foam. Smooth-On www.smooth-on.com 800-762-0744
  2. The Flame Out foam might work, I emailed Smooth On to see what they have to say. Balsa would be too time-consuming. It's a rather irregular shape that has to be very precise and also has a bent piece of wire going through the center. I was looking around at epoxy mixed with microballoons last night, that might work if I could find some really cheap, low viscosity epoxy.
  3. This lure will be poured out of soft plastic. The foam will be for floatation only, and is suspended inside the soft plastic. I have a 4-part mold for the soft plastic bait, and the cured foam piece is suspended inside of it when I pour the plastic in. Hope this makes sense...
  4. I need some foam that, once cured, can resist 350 degree plastic. I'm using a 2-part bondo mold to pour the foam in. I've been experimenting with 8lb urethane foam, but once it gets much above 150 degrees it starts expanding, cracking, and much worse releasing tons of gasses. It doesn't seem to matter how long I let it cure, I just tested a piece that I poured two weeks ago and had equally bad results. Coating it with epoxy doesn't help. I need something that can be poured into a 2-part mold, is buoyant, reasonably tough, and won't react when melted plastic is poured next to it. Thanks for any ideas...
