i have built some pretty complex shaped parts that i would not trust to ever come out of the mold if i used a auto wax for a release .
parts will pop off the mild if you use the right release for them .
that is one of the things i never think about ! with complex shapes you may have to blow air between the mold and the part to pop it out and at time depending on the size of the part get some one to help me pull it from the molds .
last week i used the hole nose of the car to pull a mold from it took 4 people to pull the mold off the car . next week i have to do the rest of it thats from the wheel openings to the doors and to the center of the hood . when i'm finished there will be 3 pieces one of the nose to the tops of the wheel opening then two right and left sides from the top of the wheel opning to the doors to the center of the hood .

Has anyone used solarez uv cure poly resin? I like that it is low-voc and doesn't use mekp as a catalyst. It goes full hard in 3 mins in sunlight but you can half bake it for in between coats. Also any resin you have left over that hasn't been in the sun can be put back in the jar.

I'm thinking ill use a normal tooling gelcoat for the mold and then the solarez resin for the 3 layers of mat.
