hmmm, I'm not sure about that one. You're dead on about the moisture when it comes to urethane, but this seems odd. What happens if you don't pre heat your mold? Does the left over material in the mixing container also have little dots after it cures? Do you have a pressure pot? I'm pretty sure that would take care of any bubble issues you're having. We'll have to get Mike the Goop King to weigh in on this one. sorry you're having issues. we'll do the best we can to help you get it worked out.
