I have just started construction of a Pygmy Artic Tern '14 and I have a couple of questions:

1) In my very first batch of epoxy mixed together in an effort to glue the butt seams together, I somehow managed to not put enough hardener in. It has been over a week and it is still slightly tacky spots. Any suggestions for handling this? Or just wait it out until it is completely hardened (assuming it will completely harden).

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??????

Thanks!
