Covering with a glue stick is another option for those who do not want to use the spray adhesive. The process is similar to the spray adhesive method, except instead of spray adhesive, you use a glue stick. To apply the glue, simply rub the end of the glue stick onto the tops of the wing spars and the tops of the ribs. It may be beneficial for you to buy a colored glue stick, one that goes on colored but dries clear, so you can see where you have applied the glue as you go. Once the wing is coated with the glue stick, then flip the wing over and lay it on the tissue paper just like the spray adhesive method.
