We use masking tape within 1/16 of inch of wing joints drill 1/16 pin holes in both half's then put on epoxy. When you put the two half's together the extra will come out and then use alcohol to wipe up the extra then pull tape off and furnish wiping the joint and your done. you now have a very clean joint. the pin holes you put in will act a rivets keeping everything snug and tight
Its a good thing they have spell check or I would be in big truble as my fingers do not always hit the right keys lol------
