Often stress cracks like this are caused when there is a partial release failure, so it hasn't completely stuck but it takes too much force to demould. The bits of stuck gelcoat also tell me this was the case.

How well sealed have you kept the bottle of Easylease? When you are applying it, do you keep the lid off or do you put the lid back on straight away before applying it to the mould? Chemical release agents are very sensitive to moisture and are hygroscopic by nature, so you need to be quite careful with how well sealed you keep the bottle and how often you expose it to the air.

Mould coating - do not know this products, but many standards coats react with release agents. Mould coating has to be fully cured of course (some products needs even 14 days after coating for full curing. 3. Release agent itself. Carbon fiber sheets and composites . www.dexcraft.com
