glue that i use is called techniglue. It is a two part epoxy mixed at 2 to 1 ratio. It is strong as hell the surface that you used the glue on will break apart and not the glue. It is water based so can clean up with a damp cloth, you can pigmentate it , can use as a fillet, and is light weight. I use it on all of my planes and you can turn the pop stick upside down and it wron't drip and does not run
