Dry Spots on Fabric After Infusion

Hello,
  I have been infusing my parts lately and each time I pulled the part, I have dry areas on the surface.  Seems like the fabric is not fully wetting out.  

Or is it due to the super 77 adhesive I'm using to hold the carbon fiber in place?  I mist it a few passes on the carbon fiber and press it into the mold.

Who are you guys referring to with the questions?  I'm not sure if I'm supposed to answe those questions or not???

But yes, I'm degassing the resin but I ran a test and even without degassing, I did not have an issue with any voids.  I'm currently not working with polyester resin, I'm awaiting on epoxy infusion resin which should come on Friday and I will try to make another attempt.

Thank you for all your input.  I will make another attempt on Friday and I'm hoping that this will be the last of my problems.
