FishnFreak Posted March 14, 2013 Report Share Posted March 14, 2013 Question for any of you who use Bondo products in creating a 2 piece mold: When using the Bondo Polyester Fiberglass resin for a two piece mold, do you use a clay bed? I was wondering how the resin reacted with the modeling clay. If you can't use a clay bed how do you accurately make a 2-piece mold? I have seen some pretty impressive 2 piece molds made with Bondo Body Filler. My experience with Body Filler is limited but every time I've used it its very thick and pasty. How are you able to make a pourable solution using Body Filler?. I mean I'm assuming the bondo body filler molds I say were poured... Thanks for the unput!

Travis Posted March 14, 2013 Report Share Posted March 14, 2013 I have done it several ways over the years. Hard to go wrong in the method since the final mold material is so forgiving. Of course they don't last as long and depending on how hot they get can start to warp if you don't add material to stabilize the mold. I typically have used clay on all hard masters and if using a soft master then after i pour the resin into the mold box (legos) i will just press the soft master a little half way into the mold. After it sets then pull the master and sand the face flat before molding the second half. It is a thick product for sure and getting it into fine details not the best medium. I had no issues picking up all the fine ridges on a sinking stick bait. Quote Link to comment Share on other sites More sharing options...
