Hello guys! I'm a newbie here. I just start making parts from mold and run into this problem. After I demolded my part, everything looked perfectly, no pinholes whatsoever except this milky spots on my parts. I've posted some pictures below. What is the cause of this and what would be the best solution? Thanks a lot guys. 

could the first picture, but moisture somehow? I am more asking then saying. I see delam in the second one but the cloudy look of the first reminds me of when I did a project on a super humid day and trapped moisture
