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 wouldnt bother sanding it, it typically doesnt work well and theres a chance you hit your mould which would be bad. Just layup a layer or two of 225g CSM with polyester or vinyl ester resin onto it and use that to pull it off the mould cleanly. Your mould should be fine, but the gelcoat is wasted. Better to waste it with a few more cheap materials rather than expensive ones.
