Don't count on it soaking into the surface cross grain, 
because it won't much. Getting it in the hole, however, I've 
seen CA wick over 15mm and out the end grain of my bridge test 
samples. I'd expect epoxy to go that far too.

Nearly no benefit. What you're doing is filling the voids in 
the wood structure with plastic so moisture won't have a place 
to go, and if it did, the wood is essentially locally 
petrified, which limits dimensional changes.

Play with it when you get the chance.
