Blakmax,
to answer your question when we get a canopy (off the airframe) in for repair we remove all of the old repairs that Eurocopter was doing with some wacked out resin and glass system that didn't work. We spend a lot of hours sealing the edges of the canopy with resin before we are able to get vacuum on it and inject the resin into the area that is dis-bond is at the upper post section, the repair is not small it extends from the top of the post area all the way to the lower section of the post as it begins to wrap around the lower part where the fwd cowl comes into contact. Eurocopter calls this "reinforcing". We also apply a repair to the inside of the post area. I have seen our repairs after a full season of heavy use, being here in BC they get a lot of use and the repairs are intact with no cracking. I do appreciate your info though what I am interested in is the areas that you are talking about outside of the canopy?
