Well, that got your attention.
I have a number of questions and a mixed bag of results over the last couple of months working backwards -

I have and epoxy mould, surface prepared sanded to 1200 grit wet and dry Polarshine'd coated with 5 coats of easy lease and 5 coats of Canuba wax, I thought this morning it would jump off the mould.......

Didn't stuck in various places, the gel coat stuck fused to the mould in patches delaminated from the Diolen, mould Frigged panel frigged

Can easi lease go off, I've made 12 different parts and I've never had so much pain as the last few where I have taking extra precautions, drying times between coats on the easi lease and the wax ???

I've changed to the epoxy infusion resin ??
I might have tipped a bit more hardner in there ??

Could it be curing times, did I pop it out to early ??

The mould had a talc mixed gel coat ???

Can I repair the mould with filler and sand it back down ???

Thanks Matt, I didn't realise the hardner was down to the gram and did think as long as it had more it would be OK
