Greetings,

I have a late 80's vintage Sea Ray 300 Weekender with the long,
rectangular side windows.....Of course, there are notorious for
leaking, and mine are now leaking in the worst of places, right above
the electrical panel and A/C controls.....

Finding the source of the leak has been all but impossible so far, so
I was wondering.....Is there such a thing as a water-thin sealant that
I could pour into the window channel, let it work its way through the
leaks, cure, and eventually seal them?

The side windows likely haven't been opened for 10 years, so I'm not
concerned about their operability....I just want the leaks stopped,
and I'm tired of spreading caulk to no avail....

Thanks in advance!!
