Used Pattern-Coat Hi-Gloss instead of Polyester Gelcoat GC50 for the mould

Hello Guys & Easy Composites Team,

I have used wrongly the Hi-Gloss Pattern Coat for my mould instead of the Polyester Gelcoat GC50. Crying

First I prepared the mould with 3 layers of wax (soft hand polishing) and one layer of PVA.
Than I put a thicker layer of HI-Gloss with a brush onto it.

I wanted to do a carbon fibre hand laminate after curing.
Does it makes sense now or do I have destroyed my mould with the wrong coat now?
What happens if I continue with the hand laminate now?
Does the mould will separate from the hand laminate or the hi-gloss coat?

Thanks a lot for your help and support in advance.

Key thing with infusion is do not go near resin until you know you have a good sealed bag.  If your bag is leaky, you will likely just ruin the part.

The other areas you can see on your finished part are mostly bridging related which is about ensuring your fabric and bagging stack are (and stay) tightly against the mould surface.  Trying to do that part in one piece was ambitious And it might be easier breaking it into a few smaller pieces.
