You don't need to worry about small air pockets. Do your best to clear-out the sanding dust before you glass over, but that's about all you should need to do. They'll get filled with epoxy later.

Do try to get a smooth joint, however. You don't want a big step at the seam. Of course, you don't want to sand through the outer skin either, so use your best judgement.

: 2) I did manage to mix appropriate amounts of resin and hardener while
: glueing the other butt seams. I just started sanding the hardened resin
: down to be smooth with the wood. How picky do I need to be about this. I
: have developed some air pockets in the cured epoxy and I am wondering if
: it is necessary to completely smooth these out. OR, will the subsequent
: coats of resin and glass fill these in sufficiently. Any other suggestions
: about working with this very first step??????
