Release agent for foam and polyester

Recommended Posts

I dont really know a forum for this, so ill ask here and see if someone knows.

I have an rc airplane made from foam. I want to make a copy from carbon fiber, using a mold from polyester. I dont know what sort of release agent i can use that does not get soaked in, and ruin the foam. I also want to make touring car body shells with the same materials, so preferable something that works for plastic also. Do anyone know a release agent that works? Alternatively tips to stop the foam from soaking without ruining the plane? Thanks for amswers!

My first thought was silicone spray. The only issue I see there is that it possibly will be difficult to remove. You should try it on a small piece before you spray it on the hole plane.
