Re: foam for flotation

Like Doug said, stay well away from that spray foam stuff.  

Pool noodles are great and cheap but you need to seal any parts you
have cut with a heat gun or they will absorb water over time as well. 
This isn't critical as it takes a year or so of use before they soak up
water and are easy to replace.  Just make sure you have enough stuffed
in the hull to make it float.  Do a float test in the shallow water.

Another foam to use is closed cell foam. Like what they use for those
thin camping sleeping rolls you see in Kmart - the ones hikers use. 
These don't soak up water and are very buoyant.  I try to use this
stuff in my boats.
