Hi Dave, I' m pretty sure this is the discussion you are looking for on the VhB tape and Silicone method. See the Sailmagazine link below.
I saved many technical discussions in a folder over the years.

I like the sailing anarchy suggestion - with coincides (fairly closely )with Don Casey's recommendation http://www.sailmagazine.com/boatworks/replacing-fixed-portlights He recommends double sided tape and Dow Corning 795 sealant. The one difference he suggests using just the double sided tape initially - then squeeze the sealant into the gap after the window is in place.

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.

The windows and hatches had been replaced by the previous owner. Hatches were done right, the side windows were bedded in silicone, not right. I had to re-bed one of them already but did not get all traces of the silicone off so it did not take. Need to do it again as soon as possible which will involve removing the window, scraping clean and then wiping the cabin side with acetone and re-bedding with 5200. The question is – there are no mechanical fastenings? Should I add screws every 4” or so or create some sort of method to press the windows in place while the 5200 sets? Anyone come up with the perfect jig to do this or is it better to add screws? Large custom bar clamps? Rex & Jennifer Delay www.
