Whoever says canopy glue is the same as elmers glue.... well.......... I just recently tested a number of adhesives and selected canopy glue to secure aluminum sheeting to my 100 inch wingspan BT-13. I sheeted the plane with .080 aluminum roof flashing and atttached it all with canopy glue. The canopy glue is flexible and with the expansion of the aluminum in the Florida heat, a non-flexible glue like elmers, epoxy, or superglue would not hold, too brittle. Canopy glue is also wonderful for coating the threads of screws and bolts to keep them from vibrating out. Use it like loc-tite, its really amazing stuff. Here is a picture of the PROOF.
