finishing touches [TANKS]

[adt22-at-drexel.edu]

I'd like to make my woodwork a little water resistant.  What's the recommended 
approach (cheap and fast are good)?  I got a quart of titebond II (should I have 
gotten a gallon? any application tips?).  I figure I'll have to take all the stuff 
out of it so I can properly seal all the places that bolt through to the outside.

I'm mostly worried about the hull, but is there anything to do for tracks that have 
already been assembled?  Is it a lost cause to try to seal it?

Thanks,
Amir
