One of the windows on my1981 Sea Ray 260DA has a persistent leak. The window is about 11" x 90" and is a slider.

It's hard to tell where the rain water is coming in exactly, as it can run along the aluminum frame and show up elsewhere.

I could run a bead of sealer around the window edge, but the proper way is to pull it and reseal it under the flange.

What sealer is generally used for this?

I know in the RV world RTV is frowned upon in favor of a Dicor sealant that is oil based and doesn't really harden.

So what are the suggestions for sealant?

if its the internal glazing strips, you may need new ones (they dont last much past 25 years)

for the external seal to the hull, the window was probably bedded in with butyl tape and sealed with 3M 4000 UV

The leak is from the external seal to the hull.

I'm going to get some 3M 4000 UV, do you think that will be enough without also using butyl tape?

I think you should do some more research on the sealer.I dont ever recall anyone using that sealer to seal out water intrusion in a window.I just resealed the plastic in a bromar hatch and it called for GE ultraglaze ssg4000 structural silicone.charlie
