Thanks, Josh. According to Uline, which sells VHB tape, there many different varieties.

Silicone makes everything it touches nearly impervious to any other adhesive or sealer in the future, and most tapes will break down after a short period of time resulting in a messy residue which will necessitate the used of a goo remover which may, like silicone, make future adhesives ineffective. "Unless you are sailing in the rain I suggest a tarp while in the slip." The "right" way is generally accepted to be 3M VHB tape followed by Dow 795 to seal the edges. Mechanical fasteners would seemingly improve the longevity of the seal but destroy the look and would likely prove to have unforseen disadvantages.

Unless you are sailing in the rain I suggest a tarp while in the slip. Later you can do the job right and not have to remove any calk or tape.

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!
