I did the windows myself on my 34 over 10 years ago. Biggest issue was the plexus the factory used to attach the original windows would not release causing damage to the gel coat underneath which required repair. Major PITA. But all is well that ends well. Windows still going strong no leaks. Used the SIKA 295 system. Key to stay within shelf life and follow directions exactly. Sensitive to temperature and humidity. I used small pieces of 1/8 inch tubing to ensure window was proud to the gel coat and screws at each corner to hold plexi in place while the SIKA cured. This ensured adequate thickness of the SIKA so it could flex as the boat moved. Just removed screws and filled holes with SIKA after it cured. Be sure to mask and tape everything anywhere near the windows as is impossible to remove if some gets to an unwanted surface.
