Hello, I am casting my projects upside down on a smooth plastic, almost glass surface. I cast this way as I place my furniture pieces in the resin on my second or third pour ( curved wood). I notice a soon as I pour my first coat, a haze like film appears on the surface, almost seems to thicken instantly. It is only obvious at an angle initially. As the project cures, over a period of a few days this haze goes scally/off white and noticeable looking through the resin once removed from the mold and flipped over. As I have curved wood in the resin protruding out is is impossible to sand out/remove. How do I avoid this initial haze? I have attached two images. the close up is the image looking through the top, where you can see the white scales.
