I had a horrible fit (gap) of my boot cowl to windshield when i finished my plane. I didn't realize it was so bad til i was done. I lived with it for a year and couldnt take it any more. I had to fix the gap. I put wax paper on the windshield and built up a fill with superfil. I shaped it and then fiberglassed over top of the superfil. I then put a strip of rubber window seal from home depot on the base of the windshield. I think i have a leak proof seal now and it looks a lot better. Pics are still primer, will be painted blue.
