SpoonMinnow Posted December 27, 2017 Report Share Posted December 27, 2017 I'm going to order silicone to duplicate some lure designs but still might use plaster. The coat I had used is no longer sold. Any suggestions? Quote Link to comment Share on other sites More sharing options...

Travis Posted December 27, 2017 Report Share Posted December 27, 2017 (edited) Gong to get answers all over the board on this one. I use Devcon thinned with acetone. Over the past 14 years or so I have tried about all the usually ones that get mentioned and still have always went back to Devcon . Elmers is popular with some, modge podge, high temp spray paints, some just coat heavily with an spray oil (WD 40, PAM, etc..) and countless other products that fall into the same basic categories. Really boils down to what you are capable of doing and the results you are willing to accept. Edited December 27, 2017 by Travis Quote Link to comment Share on other sites More sharing options...
SlowFISH Posted December 27, 2017 Report Share Posted December 27, 2017 You can use almost anything that will take the heat... I've even used moisture cured urethane's I didn't like that I bought for coating hardbaits.... key things to figure out is will you're coating hold up to heat and how well does it fill into small areas shoudl your mold s have fine details.

SpoonMinnow Posted December 29, 2017 Author Report Share Posted December 29, 2017 (edited) Bondo fiberglass resin sounds like it would be difficult to use. Quote some just coat heavily with an spray oil (WD 40, PAM, etc.. Would the plaster cavity surface hold up after many pours?

Travis Posted December 29, 2017 Report Share Posted December 29, 2017 I don't think the molds hold up well unless using an epoxy type of sealer. Only molds I have used "oil" with were bondo body filler molds. I soaked them liberally with an oil based fish scent. These typically are short term molds. Really dependent upon the bait and its simplicity in regards to undercuts and details. Typically they were three inch senkos until mold makers started making the smaller senkos in aluminum. 1 Quote Link to comment Share on other sites More sharing options...
SlowFISH Posted December 29, 2017 Report Share Posted December 29, 2017 Agree with Travis - you'll need something that hardens a bit to help the molds avoid chipping at the part line and thin areas. At one point I was mixing a heavy dose of elmers white glue into my plaster when I poured the mold... this seemed to help give it strength as well as "seal" it up a bit. I'd make enough to cover the bait with the POP/Glue mix - then backfill the mold with straight POP mixed "normally" - seemed to work well and I noticed I didn't have to try and go crazy sealing the mold as you would with a bone dry pop mold.
