Rear window seal?
 

In replacing some trim pieces, I noticed that the rear window was completely loose in the opening...

What is the proper method of sealing the rear window? Do I use a butyl seal? And where would I get this?

Thanks!

Mike

Yes - Use a butyl seal. Any auto parts store will carry it. Just be sure to clean both the window and the frame real good before installation and use the little rubber spacers to center it in the window. I think that the butyl seal comes with some.

There is a tech article on the 914fan web page http://www.914fan.net/ Good luck

Beware! Ive been told by a reliable source, and experienced for myself that butyl rubber does NOT stop water. I ended up taking my car into a local glass shop and for $15 they did a great job sealing it and making it pretty and I got a no-leak guarantee.

I have removed several windshields and installed three that were sealed with butyl rubber. I cannot see any way at all that water could get through the caulk if it is installed correctly. My chebby truck windsheild was installed from the factory with butyl rubber caulk and has never leaked a drop. I wonder why your good source would say that?

You have to be very careful when you install it. Don't get the strip twisted or kinked. Also - don't touch it on the sealing surfaces. I found that it can pick up dirt and oil off your fingers and then it does not seal very well at those points.

You also need to give it time to cure. I replaced my window and then the next day towed the car backwards. The air pressure was enough to push the window back out.

Thanks everyone! I've also heard of some sealing material made by 3M for this purpose which is applied with a caulking gun...but it seems the butyl solution should work!
