Dave,
From past experience, I can only suggest the following:
Find/build/buy/scrounge a length of raingutter longer than the bamboo shafts.
[Not sure what band/s you are looking at, but 16' for each might be
long enough.]
Polyurethane will work, but you can purchase marine spar varnish in
5-gallon [or larger] quantities for less.
Use the raingutter as a trough to soak the bamboo for an extended
period of time.
You will want to cover the trough while soaking so it doesn't
evaporate or get 'thick'.
You will need a 'drying stand' after removing them from the trough. I
suggest using two very thin edges of metal for them to rest upon.
Keeping the shafts from the weather is another problem!
Good luck
Don
