Fred,
You are right.... if used properly. And every actor has his own method and so goes the modeling ways too. Poly-u is by far lighter then sourgum. I used to use the sourgum stuff back in the 70's but have since switched to the poly glues for sheeting wings. The poly glue when used with carbon fiber will also produce an extremely strong setup in the wing. My pattern plane has over 525 sq in per panel and they only weight 14.5 oz RTF w/servo.
Either glue works good when the proper application is used. Soooooo sheet away.
Smooth Flying...

even at that you need to put a load on the shucks for awhile and sourgum haha will release in the heat of day in the summer.to each their own to learn and like or dislike
Not if you use the product correctly, but then that's a much larger issue with polyurethane glues.
