Another glue worth noting is, big surprise, old school model airplane cement. I love Ambroid! I used it as recently as about one hour ago. No allergies, no fumes, a delightful scent that reminds me of my childhood days building Guillow's kits, plus it sands like a dream. I would never use anything else for edge joining wing sheeting or other external joints. It sands down to an invisible seam, unlike CA which always leaves a seam visible through covering. I use Ambroid on everything from indoor rubber power under 1 gram Mini-Sticks to 2 meter fire breathing pattern planes. I'd use it on bigger if I flew them.
