DingerBaits Posted February 9, 2017 Report Share Posted February 9, 2017 Just carved a pretty slick looking bait out of PVC and looking for suggestions on if i need to seal it before I make a mold out of it. It seems like any type of mold would stick to it due to its porous nature. Any suggestions would be great. Quote Link to comment Share on other sites More sharing options...
JRammit Posted February 9, 2017 Report Share Posted February 9, 2017 Yes, you'll need a smooth surface to pour the mold around.... Weather it's RTV or plaster 30 minute epoxy is my choice... Thinned down with a little denatured alcohol... Just make sure and rotate the master until the epoxy begins to harden, or you'll have droopy spots Quote Link to comment Share on other sites More sharing options...
Travis Posted February 9, 2017 Report Share Posted February 9, 2017 For masters I usually stick with a spray on shellac. Dries very quick, one can build multiple coats and be done in 5 minutes and keep everything crisp. Epoxy in my opinion is not ideal for masters especially for anything with detail as their is some loss of crispness in your final mold. One can overemphasis the detail in the master to compensate but I just don't think it turns out as well. Also if you need to rework the master shellac is no issue and epoxy is a pain. I have also just skipped the seal coat and just use a mold release agent. You can rub you bait down with Johnson's Paste wax, let it dry and buff it off. Vaseline can be used but can create issues unless using RTV. Mann's MoldEase one I typically use when I need a mold release. Spray paint will also work fine and have used it frequently on non detailed baits. These all end up taking a little more prep time with detailed baits as you have to wipe out of crevices, etc.. 1 Quote Link to comment Share on other sites More sharing options...
