If you plan to fill all 11 mold shapes with resin, then spray the entire mold with mold release. I planned to only fill about a third of the shapes, so I covered part of the mold with paper towels when spraying the mold release and left them there while it dried. That way, I could remember when I returned which shapes had been prepped for the resin.
Make sure the release is dry before starting the next steps. Normally, I will prepare my molds well in advance, at least a few hours to be totally sure. However, I live in a very humid climate, and anything takes longer to dry down here.
