When I sealed my wings, I bought some of those empty caulk tubes from Wicks (they call them “Epoxy Tubes”) to help the process. After pre-measuring and staging several batches of Hysol (I think it was 9339, whatever the blue stuff was), I spread a thin coat on the bonding surfaces of the upper wing assembly, then a thin coat on the (previously marked) corresponding locations on the lower wing skin, then mixed up a fairly large batch, added a little flox for body per the manual, loaded the tube, and laid a bead of Hysol on the spars and ribs of the upper wing assembly. I remember it took longer to mix the Hysol than it did to lay the bead.  Like Jim, I added a ton of weight to weigh the lower wing skin down. Those tubes really help ensure you get enough epoxy on all of the bonding surfaces.
