Do NOT use 5200. Here is one way to do it: http://www.cncphotoalbum.com/doityourself/portlight_replace/page01.htm
Here is another way to do it: http://forums.sailinganarchy.com/index.php?showtopic=133986&hl= Here's another way: Clean all traces of silicone from the window and frame. This will take roughly forever. I used a product I got from an auto parts store called "Acryl-Safe" which did a good job. You could also try any number of citrus-based silicone removers. Clean off all the remover residue with Interlux Special Thinner 216. You could try rebedding without screws. I opted to use screws on 6" centers, 4" would have been better. Drill the holes slightly oversize and use a washer under the screw head. The sealant is the next step. I used Life Seal (NOT Life Caulk!) because it has good adhesive qualities and does not interact with the acrylic/Lexan (whatever you have). If I was starting from scratch, I would use Sikaflex 295 UV with the special primer and skip the screws.
