Hello friends, 

I made two pieces of carbon fiber by the hand lay up process + Vac bagging and I'm having problems with areas as per the picture. Defects such as air bubbles and dry regions.

I am not using Gel coat because I will use clear coat when finalizing and I do not use tacky spray because it is a cosmetic piece.

I'm using material / resin ratio in 50:50 and vacuum at -28 in.

Where can I be going wrong?
