BTW... Do you have the problem of your laminate baits splitting apart at the "seam"? If so, what brand of plastisol are you using.
I won't go into why but so far, only M-F and the new CC plastisols have resolved this problem completely. Other brands will give you issues for sure. There are some ways around though.
Even with injection, you can notice other brands won't "stick" well to the other side if you happen to pour the belly of say a frog and then inject the top portion a few minutes later.
I am almost certain this has to do with less expensive PVC particles being used (large ones) so they can't form a bond real easy unless fairly hot.
Anyway, I digress.....
