Traces, streaks, and matte on the surface of the mold?

This phenomenon occurs in the mold because the product or model to be copied is not polished or polished. Because the model or the product itself is not smooth or perfect, the product or model to be copied will not be aesthetically pleasing or smooth if it has not been polished or polished. In another case, when the mold release agent is applied, even if the paint is not evenly applied, the mold is not smooth.
