Its hard to tell from your photos exactly what it is.  Almost looks like marks on the surface. Is it actual pinholes or bubbles trapped below the surface?

Are you using a spray adhesive?

Try using acetone or soft polish compound to eliminate these marks.
note: take care with the soft polish compound, you can reduce the resin and touch the carbon..

Hello my friends. Today i had the same issue . Like air bubbles trapped in but i am not sure. If you check the photos clearly you can see that they are not on the srface but a bit deeper . Like a bubble which has not blown.What do you think ?

You have tried to make a piece without adhesive spray?
How long you allow the mold to dry before starting the infusion?
Your mold has a perfect gloss finish?

I don't use adhesive spray. i changed the wax with an other brand and i have not any more these marks
