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?

Dare to KNOW! The written word is the only truly efficient vehicle for transmitting a complex concept from mind to mind... 103% of all people do not understand statistics... Do not adjust our mind, theres a fault in reality :-)
