Sealant for windows

[rickasbury]

I pulled a window out looking for a leak ( was not there) and need to re seal it- I'm sure I don't want to use anything I can't get back apart.....what is the sealant for this application??

Any silicone sealer will probably do the job but my preference is Permatex's Right Stuff. It's thicker than most and stays put on vertical surfaces to fill wider gaps better than most sealers.

I bought a locktite product for exterior doors and windows, a polyurethane sealant....that work?

I would use 3M 4000 UV

isn't the 4000 more of a permanent adhesive? I want to put something there to seal it but if I have to replace the window, I don't want to have to cut it out with a chain saw!

5200 is more of a permanent adhesive. 4000 UV is a sealant for windows.

• High performance, medium strength bonding allows for disassembly
• Excellent UV resistance
• Color stable sealing
• Above and below the water line applications

I'm reading also the poly stuff is more of an adhesive also...will put that in the shop and get some silicone...
