It does work Rich. It also works for fuselage doublers, wing sheeting, ect. Years ago when we discovered that white glue sometimes sealed itself in the joint and didn't dry. So I tried coating ply and balsa with thin coats of white glue and let them dry. I put them together and with an iron on it's hottest setting I heated the ply moving over the entire surface until I could see some movement of the glue along the edges. I then weighted it with a flat board and bricks and let it cool. Then I dissected it, the joint was full and strong. I used that method a number of times over the years though with the patience of age I now use epoxy. Back then I could have both sides glued and on in about an hour because the white glue dried quickly being completely open. Not sure all white glues are created equal though, my experience was with Elmer's.
