laminating - air pockets?

[ElBichoMalo]

Started my first laminating today (just a small "stern seat" recore job), but I think I am going to have a problem with the finished product. Here is what I did:
Using all fgci products (they are local for me) polyester resin 1.5% MEKP mix, mixed in milled fibers, used to "glue" down the core material. I used a composite "foam-like" board from fgci. Can't remember the name of the product...starts with diab... same stuff Gause uses (because the sheet I bought was earmarked for them - guy says they buy it weekly - Gause is local too). I mitered the edges of the core, glued it down and let it cure overnight. This morning I did this:
coated the core/hatch with resin, then layed a layer of 1708, wet out, using a combo of a ribbed aluminum roller and a chip brush. Looked nice, but then I kept thinking there was trapped air. Everytime I would try to roll it out to the edge, it just made it worse. Everything I read says the whole point of rolling is to get rid of the air. What am I doing wrong?

P.S. I also added one more layer of 1708, slightly larger than the first, while the first was still wet. It this the right process? The whole point of me starting with such a small meaningless piece was to get this learning curve out of the way before something important, and I am glad I planned it this way. Now help me!
