Gfeldman Posted December 9, 2021 Report Share Posted December 9, 2021 Hi all, Has anyone seen tiny cracks (as seen in the attached photo)in their canopy which seem to result from vibration? Any ideas about how to damp this shaking? George Feldman N33GF Quote Link to comment Share on other sites More sharing options...
Jim Lee Posted December 9, 2021 Report Share Posted December 9, 2021 George, those are scratches on the canopy made by the upper cowling when it is removed and put back on. There is no room between the cowling and the canopy when it is open. Always close the canopy when dealing with the cowling. Vibration can cause cracks around nuts and existing holes, such as around the window vents but not in the middle of a canopy such as this. Never overtighten the nuts on the canopy windows, and never lift or shut the canopy by the window to avoid those cracks. You can take out some scratches with Micro Mesh which works very well. But you have to be careful not to sand too much or you will induce distortions into the canopy. There are companies which can take most scratches out of a canopy, such as Fidel Ramirez in Moriarty New Mexico. He is a master. Quote Link to comment Share on other sites More sharing options...
Gfeldman Posted December 14, 2021 Author Report Share Posted December 14, 2021 Hi Jim, the cracks shown in this picture have gotten worse over time. The canopy has not been removed since it was installed by the factory and I never have opened the canopy using the window.Thanks for the info. george Quote Link to comment Share on other sites More sharing options...
Gfeldman Posted December 14, 2021 Author Report Share Posted December 14, 2021 Jim sorry about my last reply. I don’t remember ever contacting the canopy with the cowl but it is possible. george Quote Link to comment Share on other sites More sharing options...
