To Vac or Not to Vac

[427 Cobra]

That's another reason why I wouldn't trust pressurising the mould material, just for safetys' sake! Most people make two part moulds that are hollow and don't have the durability that I incorporate into all my things. I want durability, which is why I'd just use an epoxy fibreglas mixture for the product, and forget about pressurising, or degassing the mould entirely.

What are you trying to make with this, if you don't mind me asking? I mean is this a two part mould, or is this a really big solid part that will need two sides to complete?
