I was nearly sure about you using sprayed GC on this one, because I recognize slight prints through it, marking the cloth, don't know if you see what i mean. The cloth is not completely flat, due to slight spots left by the spray gun. This is a concern to me, as I'd like a perfect cosmetic part, and I'm looking for a solution to get rid of that. A solution would be to slightly sand the GC once cured, to flatten it. Sounds like you are either laying down the GC50 too thick or with too much air pressure. If applied correctly you should not need to sand it before lay-up, sort of defeats the object of using it in the first place. Carbon Copies Ltd Edited 11 Years Ago by wozza

I will add another 3 or 4 layers where items fasten or strips where I need to reduce flex from wind ect.... The total weight is sub 1Kg... The second photo shows some heavier carbon which was 400gr but I stopped using it as I ran out of the 400gr pre-preg and didnt want to buy 25sq m just for reinforcements..
