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.

If you work with gelcoat, I would always advise to do resin infusion instead of wet layup with vacuum bagging. In fact, even without gelcoat I would prefer resin infusion. If you have bagging materials and a decent pump, there is really no reason not to infuse. The part will be of a much more consistent and better quality. And it is just as much effort.

I thought about it. But do you think I can avoid the air bubbles with an infusion? The form is quite complex.
Does the layup fit the shape perfectly with infusion? Of course I would prefer it too. Also because working with a wet layup is s*** Smile 

Next, is the infusion mesh absolutely necessary?
