For my first half of a two part mold, I mix yellow carpenter's glue into my pop, fill my mold box, lay in my soft bait masters, and then put it in the oven at 170 for an hour+- to cure/dry out. Once it's dried out, I clean up the surface if it needs it, and then I coat the mold half, with the masters still in the cavities, with diluted D2T, two coats. I let it cure over night, spray the first half with PAM, and then do the same thing with my second half.
Once the second half has set, after I've pried the two halves, I put the second half into the oven. Then I remove the masters from the first half, and coat the cavities with diluted epoxy, two coats, to make sure it releases well.
Once I'm ready to coat the second half with epoxy, I coat the open cavities at the same time.
For me, it's a three day process, or the epoxy stays tacky.
I spray my molds with PAM before each pour.
