    I've got the opportunity to buy some spray can mold release at a really good price (business closing down) - I'm struggling to find any information on it though other than that it is a non-silicone mold release. Would that be suitable for composites or ?

    Silicone based can create havoc later with painting, that's all I got.

    I'm a Manufacturing Engineer for Meggitt in Advanced Composites. It is widely emphasized at work everyday that silicone and uncured composites ARE VICIOUS ENEMIES! Major aircraft companies prohibit silicone-based products from being anywhere near their parts that are being built and cured. They even go so far as to say tape with silicone-based adhesive is prohibited and we must use rubber-based adhesive tape in our build rooms.

    Interesting! Got the cans late today for $10 per box of 10 cans so hopefully the product works well
