So I am using AeroMarine Epoxy Resin #300 and Hardener #21 along with MG Chemicals Epoxy Mold Release. I mixed the epoxies together and placed my first coat on the silicone mold and let it stand for a couple hours. Then I placed the carbon fiber sheets down and coated each layer with more epoxy. When I take it out, I'm getting a white film on the surface that is touching the silicone mold. I've tried searching for the solution with no luck. So I am hoping you all can help me. Thanks you. For those curious, this is a UFO body for a quad copter.
