Hi All - Anyone know if I will have any issues using polyester body filler to make a simple mould from which to form an epoxy part ? Propose to use this as it's very quick and easy to shape. Will be using Easy Lease. Thanks

This won't work, except you use 2k clearcoat or something similar to finish the mould. Pva as release agent will work, too. Epoxy doesn't release well from bodyfiller if you use regular release agents.

Ok thanks. Much appreciated.
