HI!
My carbon fiber part got ruined since it got stuck to the mold. I sealed it with epoxy and applied 1 layer of mold release wax. It did not work.
I have to try again and I bought Easycomposites PVA Mould Release Agent »
I will get it in about a week(it's holiday times) but I cant wait to try again and am thinking about using silicon as a releas agent.
Will silicon work as a good release?
Have a great newyear!
Cheers!
Joel

You have several issues here: your mould seems to be made of wood and body filler. These are surfaces, wich are really difficult to get a good release from. A coat of 2 component (!) Laquer would be ideal to seal the ge surface.
A single application of release agent on a new mould is very risky. Usually recommended are at least 7 applications with at least 20 min in between.
Wax is a very old school release agent. Today's standard are chemical release agent like easylease. These are superior in every way. Pva is kind of outdated as well. There are only a very few special circumstances in wich i would recommend using pva. Your would would will likely cause problems with tge water based pva.
