The heat idea works fine on dried glue also. When putting thin cap strips on (1/16 inch thick) I often coat both the cap strip and the rib then let them dry. Now, just iron the cap strip onto the rib. It takes a pretty hot iron as you have to heat through the wood which is a pretty good insulator. You can use the heat sealing trick with alphatic resins very well on covering also. If you get a loose edge or peel back, just coat both surfaces with alphatic resin, let it dry, then iron the covering back down. It will stick better than the original backing. This technique works well on wood that has been fuel soaked also.
