Water proofing

I've just decided to complete a 'Puddle Jumper' I started 14 years ago. Not been modeling lately so first I must repair mice chewings!

This balsa plane will obviously get a little wet during my relearning period. How do I water proof the wood before I cover the structure? I'll cover it with monokote since that's where my experience rests.

There are "sealers" at hobby shops, and "airplane dope" provides a good anchor for monokote unless you stand near an open flame when the vapors are coming off the wet dope (Dangerous!)
Water-based polyurethane varnish is cheap, safe, and inert to most chemicals we encounter. Not affected by water after it dries. or oil, or nitro, if you haven't gone electric.
