Hi all, I have done some carbon wet lay in the past with good success. Have decided to try the uni mould and have stumbled across a problem - the gel coat started curing during application and went lumpy before I realised and had brushed on an area. I didn't have time to smooth the rest out eithwr as it would have curdled too ! Is this done for or can I just apply second goat as normal once tacky ? In other words is this going to show through and effect the final mould ?

See picture below to see what I mean !

Many thanks

Everything will show up on your final parts, even finger prints. Personally I would correct it in the mould, but it's up to you whether you correct it in mould or on the part.
