I while ago i asked aboute polyester moulds and epoxy infusion...

U answerd me to try with pva, it would woork if the moluds is old.

Now ihave tryed one time with pva and one time with easy-lease and it dosent woork so good.

I wonder if i can spray my moulds with pu carpaint?

I have some trouble with demolding..small parts of epoxy stick to the mold..

Matt explained that the polyester let go of the solvent for a long and the epoxy does not like where to stick it a little in molds.But are the molds old i can work werry well.
So my idea is to spray pu varnish to seal off the polyester.
