Well,
My first mold came out okay, my first cast went well until... I demolded it. The shape is fine and there are no airbubbles, but it didn't fully cure, part of it is still wet - I even waited twice the recommended time before demolding. Will it eventually cure fully? Or stay perpetually sticky? Any help/tips appreciated. FYI, I am using Smooth-On's Smooth-Cast 300 liquid plastic.
