Just watch out that the chemical release does not contain silicone, which will bite you if you try to paint it later. You will get fisheyes.

steel moulds i would say are the pinnacle of moulds especially for mass production of quality parts.

as for release agent, you don't have to use any particular one but chemical agents are better than pva. pva has its place but its like carbs on a car, they work but they have had there day. wax and a product called ease lease is the preferred choice i would say

Hello to everyone,
I'm new of this forum and newbie about infusion.
I have some questions:
- Is it possible to use a steel mould (zink finished or black e-coated) to create pieces with resin infusion?
- Which Mould Release Agent do I have to use?

Thanks
