That could be a problem. It's been decades since I worked much with 
balsa, but I don't remember sealant being available in spray form. It 
may well be now, but spray "paint" tends to be thin, whereas you're 
looking to fill the grain, which either needs something thicker (and 
thus requires brush application) or is going to take a /lot/ of coats to

get a properly smooth finish, possibly requiring sanding down between 
each coat to avoid altering the shape of the model. I'll happily be 
proven wrong, but those are my recollections from messing about with 
balsa (for model rocketry) once upon a time.
