Hi all,

Im still having some problems with the xpreg in gelcoat moulds. When i use aluminium moulds all is good. When i use the high temp gelcoat moulds i always get a dry finish on the mould side. I tried some longer times and diffrent temperatures but i keep getting these results. I only use breather underneath the mould but that always worked for me and only the bag where it it packed in to press on the carbon. Does anyone have a clue what could be it or what i can try?

So a little update,

I tried various temps and soaks but the end result is the same, always these dry finishes. I tired a little 5x5cm piece same 2 layers in the same mould and this comes out perfectly. What i am doing wrong? already tried with perforated release film and peelply on the back but same results.

Result with small carbon layup in same mould with same times:
