I discovered, much to my chagrin, that diesel softens 5200. Also a heated putty knife or wire.

IIRC it came out about 2 or 3 years ago. Probably a great demand among folks who have used 5200 for a permanent seal on something that should have not have been permanently mounted. If I’m not mistaken, you can buy the solvent at West Marine. But I don’t think that 5200 is a suitable material for bonding the acrylic windows. My recollection is that 5200 will not properly bond to the acrylic. Perhaps someone else on the list can confirm that? The latest discussions on the list seem to agree 3M tape is the way to go for bonding, with a sealer to seal the windows. Before that is was Sikaflex295 with the appropriate primer (which is what I used very successfully to rebuild my A&H hatches). Before that it was Plexus, which was what was apparently used for the OEM installation. Makes me kind of happy that both my boats have the old aluminum framed windows sealed to the cabin top with butyl. Every 10 years or so I replace the crazed lenses and install new EPDM seal and rubber splines. Not nearly as stylish, but a whole lot simpler and less expensive.

He claimed this was then the best adhesive to use for windows and other deck hardware instead of butyl tape. I had planned to have the yard use the 3M tape to hold/seal my new port-lights in place when I had new ones made. The current ones are 'screwed' into the coach sides and sealed, probably with butyl tape when they were done 10 years ago or so. My questions to the list are--has anyone heard of or used this stuff and could this be another, perhaps better, solution when replacing the windows?
