The instructions for the SIG Somethin Extra call for Alphatic Resin Glue. So like an obedient modeler I went to the hobby store and bought a $3 /4Oz. bottle to glue the fuselage doublers. Imagine my surprise when I went to squirt it out and discovered it looked and smelled exactly like the yellow carpenters glue in the gallon jug sitting on the shelf behind me! Now whenever someone asks me for some wood glue I always make sure to correct them and point out that they want "Alphatic Resin Glue". Don't even get me started on Cyanoacrylate.
