Rear Window

[Germain]

The rear window fell out (again). Looks like the "glue" I used hardened and the body flexed and poped it out. Is there a non-hardening glue that would copensate for body flex?

Sorry about the spelling

I've used this stuff called "Goop" before on all kinds of different stuff. It's really sticky and when it hardens it stays a kinda flexible. It might work depending on how much the body flexes. I think I got a pretty good sized tube at Advance Auto Parts. Hope that helps...

I used a 3M product I think it was called window caulk, it is a roll of black caulk about 1/2" diameter. The box is flat a nd blue/white. I've had my window in for about 2-3 years in Miami heat with no signs of hardening. Just make sure the window and channel are perfectly clean. Use even pressure and a heat gun to place the window in the channel.

Yes, by all means, you should get a role of Window Caulk. 3M makes it, and you can get it at auto body supply vendors and some auto parts places. AA has it, and so my Pelican.

It's basically a role of black, 1/4", very sticky "string" that is used to bond glass to metal. If you are able to get a complete seal all the way around your window glass (and you can see this when you press the glass into place), you will be water-tight.

It's neat stuff, and not nearly as messy as liquid caulk. It is also able to hold the window in place without it slipping down once you apply it. I used it on both my windshield and rear window when I had my '76 914 painted several years ago.

How much do you need to do both front and rear window? How much did it cost?

[JP Noonan]

I don't remember it being that bad maybe $10? One box was more than enough for the rear, I guess a full box would also easily do the font. For the front you also need about 2 dozen little trim clips to hold the trim on, ask me what happens when a PO dosen't use these clips, I'll give you a hint, it happens at about 75 mph.

The rear window also has a rubber seal on the bottom lip that is about $50. It doesn't seal the window as much as keep water from running down and collecting behind the sound dedening material on the firewall.
