Marks on part from woven of prepreg mould

Hi guys, I made prepreg form with no gelcoat (as it was always source of troubles) and visible woven in the first layer. But the final part has visible marks from the woven of prepreg form. Do you have any experiences how to get it out or better - prevent it? I can polish it away, but trouble is that the parts should be with matt finish…

Thanks for any suggestions :wink:

Higher resin content in pre preg. It’s lacking enough resin to give you a gloss Finnish over the fibres. I had a similar problem , and now I’m running 50% resin

Thank you for the feedback Timbuck. You mean higher content resin in form prepreg or final part? Thanks!
