    Just wondering about making a mold of a brown trout that I have to skin mount. I have done bondo resin molds but I know this will cook the fish, so I'm wanting to try using silicon but my question is what silicon should I use? most of the products I have researched have a long cure time. just thinking that might not be very good for the skin having it set out along time , any suggestions ? thanks in advance
  2. Concerns would be that trout tend to wrinkle and crease when trying to mold. Especially around the caudal fin area. Since you will be molding with silicone, you will not be able to retool your mold. So you will have to "chase", each cast you make. Not a big deal, if the skin movement is slight. Just a consideration. .

    Water accelerates silicone's cure time and it sets in a freezer as well. I use tube silicone to mold fish heads. It is how I would likely mold a whole fish. I'm not saying this is the only way just throwing it out there.

    Try smooth on brand oomoo 25 quick cure time I have used it for fish heads and other things, they have trial sizes you can try on a spare project and not wast a lot of money if it does not do what you want.Larry
