Hi,
I have ordered the rubber silicone to make a new mould for a damaged item. I’ve had a couple of unsuccessful attempts on glass but this is resin. If I pour a later into the base of a container and fill the space with rubber silicone will it peel away from the acrylic or do I need a release agent?
Thanks

Shouldn't need a release agent, silicone only really bonds to itself and glass (as glass contains silica).
