Hello and thanks for letting me join.
I recently built a mold for making an RC body out of carbon fiber. The mold turned out good but the final product that came out of the mold didn't look so good. I am doing a hand layup method and used part all #10 PVA over some wax to help the release.
I am wondering if the PVA played any part in my air bubble issues? I clearly need a vacuum bag setup but just looking to understand the issue.
My prior attempt without PVA (only using wax) didn't have this much issues with air pockets. I was not able to apply the PVA wet. It had to be applied in light dusting coats or it would run. Maybe that was related?
