Hookfin Posted August 4, 2008 Report Share Posted August 4, 2008 I have made a few POP 2 piece with good results...however I am trying another master full round and I can't get rid of the bubbles...anybody got any tips on getting rid of these bubbles? I am not mixing hard to cause bubbles..I pour slow...It seems they generate from detail or the petrolium jelly, I am not sure...I tap and vibrate but they just don't go away......help..Thanks Quote Link to comment Share on other sites More sharing options...
nova Posted August 4, 2008 Report Share Posted August 4, 2008 Sometimes you will get air leaking out from under the bait if its not seated well. As pop dries it shrinks away from the bait. I pour my second layer not long after the first layer sets up and I don't use a heavy coating material. I simply use veg oil and let it soak in. I also don't coat the bait with the oil. Another tip would be to not use as much water in the second pour. Use just enough to allow detail transfer. ( the coating not only stops the pop from sticking together but it also repels water and that can cause voids.) www.novalures.com Quote Link to comment Share on other sites More sharing options...
Hookfin Posted August 4, 2008 Author Report Share Posted August 4, 2008 Good info...thank you..I kind of suspected but wasn't sure..I will try your suggestions..especially veg oil, I like that...I will be posting some pics of my baits and what I caught at Clear Lake and The Delta soon but still working on getting them right...thanks for your help.

Zbass Posted August 4, 2008 Report Share Posted August 4, 2008 hookfin, nova is one of the POP masters on this site. I just started doing some 2 sided with durhams and one thing that I was tipped off to was basting the master with a coat of the pop or dwp before you pour your second layer. Since I have started doing that I have no more bubbles in the second half. Hope this helps. Zbass Quote Link to comment Share on other sites More sharing options...
Vodkaman Posted August 5, 2008 Report Share Posted August 5, 2008 Zbass, I second your comments. Since reading this tip, my molds have improved dramatically, both PoP and RTV. I use a soft brush and work the PoP into all the corners and creases that can hold trapped air and wet the surface of the master. Quote Link to comment Share on other sites More sharing options...
Hookfin Posted August 6, 2008 Author Report Share Posted August 6, 2008 I used all the tips....they made a big improvement. I do believe the air was trapped in detail and would not be drawn out until I poured the second half..The vegie oil is a big improvement! Thanks...
