Good morning. I have created a plaster mold of a face and I want to put carbon fiber on top of the mold/face and be able to remove it once the carbon fiber has dried out. What product do I use to ensure that the Carbon Fiber will release from the plaster face/mold? Which Carbon Fiber Starter Kit do you recommend I use? The face is about 1 meter high, 1/2 a matter in width and about 30 Centimeters in depth from tip of nose to ear. Thank you very much for the help and advice.

2 years ago I did a fighter jet model fuselage in plaster as a template.
I thinly painted the dried plaster with wood hardener (similar to the S120 Advanced Board & Mould Sealer), then spayed it with 2k epoxy primer, sanded with 1200 wet paper and used release wax and PVA
The resulting mould came off the template without big issues
