I came across a sealant, for aluminum to stucco. It meant to deal with 'significant' movements. I used to (temporarily) seal the head hatch, still holding up well after 2 years. It was readily available at Home Depot, the tube is on the boat so I do not have the info. The sealant is off-white, quite a reasonable match to the gelcoat.

The windows "work" significantly when the boat flexes and I doubt the sealant will work for long. My previous owner tried to smear silicon on the leaks without success. That being said, DOW 795 is much better than the typical silicone and may work better than what the PO used.

I have read up on the removal & re-installation process, and many seem to be recommending the VHB tape and Dow 795 sealer approach (or similar). I would like to seal the fixed portlights in place without replacing them for now. While they are showing some crazing, and I intend to eventually replace them (say in 18 months or so), in the short term I simply want to stop all leaks so that we can prevent any further staining of the teak. Does anyone have a recommendation as far as doing this? Should I simply attempt to carefully mask the fiberglass & plexiglass on the exterior and apply a bead of Dow 795? Would it be better to apply a thin layer on the inside? Or, am I guilty of wishful thinking? Thanks!
