Hello Guys & Easy Composites Team,

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

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.

I would not risk it. The high gloss primer is specially formulated to give extra little tack to other resins. You could even take epoxy moulds from it, wich is problematic with other polyester resins. Any other polyester would have been better.

However, you could try to sand it with a coarse grit paper, without "demoulding" the gelcoat.

Thanks oekmont.
You mean to sand it an try the laminate? That would be a better option than i‘ve done now.

These are my first tries.

Hopefully the gelcoat is giving extra little tack to the mould.
I’ve applied now just one layer of carbon fibre with few reinforcement and put in in the vacuum bag. Lets see what happens...
