I wrap my part with epoxy resin and something occur on the surface as picture.
I think temperature and humidity are issue, so please help to share your comment.
any way its the PVA or release agent?
I don’t use any release agents.
This is cover part, I cover it in carbon fiber using epoxy resin.
It looks not 100% cured epoxy and humidity.
Buy a non blushing epoxy.
the room where you were working was too hot. You need to have around 70 degree temperature for normal work.
