I got some weird problems I never had before in all my vinylester moulds I made.
I'm now using a high temp 145°C vinylester mould system  and to be sure I get no release problems on the parts  carbon fibre winglets I used PVA

So I waxed mould 7 times with high temp wax and than used pva this all went well .
After the layup the release was verry good little to good even it almost fel off but  the problem is the high gloss clearcoated carbon winglets are full  little pinoles and the mould surface also .

after demoulding I stil could peal off the pva film from the  gelcoat side verry good .

I'm using  partal coverall pva purple one because this works with the  tr104 high temp wax
