Tiara only sealed the coring with caulking. After 20 years it's time for all the caulking to be replaced. Only way to do that is to remove the portlights.

Once you do that it only makes sense to seal the coring--for good this time--with penetrating epoxy.

Then, after all that trouble, it only makes sense to replace all the portlights with the new improved design.

I heard the old gaskets were no longer available although not sure if that's correct. Would not have changed the way I way I addressed it though.
