I just finished glassing the exterior hull of my Guillemot 17, and was preparing to add a fill coat when I noticed thousands of tiny bubbles (at least I think they're bubbles) everywhere below the surface of the glass. They are all less than 1/64 inch across, and they are definately below the surface of the top layer of glass. They only occur where there are multiple layers of glass, and if you're standing more than three feet from the boat, you can't even see them.
After having finished a Pygmy S&G boat earlier this year, I got a little cocky and thought I could lay up all three layers of glass on the hull at the same time as per the "standard" layup in Nick's book. I did a saturation coat on the entire hull the night before, and I applied the epoxy using a sqeegie and a brush, and pulled out the excess.

I have three questions: first, how did this happen, and how can I avoid it in the future (other than applying one layer at a time). Next, is there a way to fix it? Finally, and most importantly, how will this affect the structural integrity of the boat?

Any help is greatly appreciated!
