They are heavily solvent based and would need a proper oven cure to stop them degassing during the mould making process. What happens is the release agent then fails where the paint is and the mould will stick in those areas. Bodyfiller does the same too in many cases. Properly sprayed 2k paints fully oven cured are normally ok though. Warren Penalver Easy Composites / Carbon Mods - Technical Support Assistant

Can also spray PVA release agent, quite reliable even on a 1k coating. But will take some refinishing to get the mould up to scratch.

It really is virtually impossible to get rid of flash tape marks without digging a massive low spot in the mould. Much better off using a 1k primer and just spraying PVA release agent as Warren said.

This won't dissolve the 1k primer and when demoulding in worst case you ripp off the two little primer patches off of the plug, but with a little acetone they will wash right off and leave you with a good surface otherwise.
