I'm curious about how important it is to peal back the covering to get a good bond into the balsa? If you adhere to the covering won't this pull the covering up over time? I am about to glue the canopy on a Gene Soucy Extra with a 160 FX and contemplating whether or not to peal back the covering or not? I have only used this stuff one time. I pealed back the covering on my Pitts with a 50 cc gasser. I normally use button heads into hard points with nylon washers, which has worked fine. With a gas engine the vibration causes the button heads to crack the canopy. Once I sealed the Canopy with Formula 560 canopy glue it has held perfect but here again I pealed back the covering to get a good bond. I sure would like to not have to peal back the covering on the Soucy if I don't have to.
