Rocketman, I didn't mean to infer that you didn't know how to prepare the canopy for glueing. I only meant that for general information for the "newbies," that may not know that. I think you've probably hit on the root cause of why today's canopy's don't accept the RC 56 glue as well as yesterdays.....It's probably the composition of the material that is being used in the manufacturing process. I'll go to "Pro Bass," and pick up a tube of the "fletch Tite," and see how it works. I'm putting together an "KANGKE" Waco, and I'm just about at that stage.
