re-gluing in quarter windows

[Longroof79]

I started removing my quarter windows(one at a time) in order to repair a few rust areas. Removing the glass made it more accessible for a cut-off wheel and getting in there with the welder.
Besides, the glass seals are pretty dry and I was planning on replacing them.

Now my question is, do I use butyl tape, and butyl or urethane caulking to reseal the glass? I would still like to paint the glass flanges before reinstalling the glass. Also, would the contact areas need to be coated with glass primer prior to adding the butyl? I noticed the original seal looked like a molded rubber gasket with a string molded into it. I suppose the butyl tape should simulate, or replace the rubber seal.

Anyone have any experience with glass resealing/ replacement?

I'm doing mine now and picked up a roll of butyl....it worked for all these years so I'm sticking (no pun intended) to the original stuff they used

I used butyl tape too. No probs yet. 😀

Thanks guys!
Is it necessary to use the glass primer on the contact areas, or is more critical for a windshield? Also, would it be necessary to use butyl caulking in conjunction with using the butyl tape? I noticed when stripping the old seal, that it also looked like the General used a rubber type caulking as well?

no need for the primer...the metal frame and seal holds it in place

Thanks Steve!
So it's as simple as that, eh? How about caulking? Is it necessary, or will the butyl tape alone do the trick?

I used butyl alone and my 1/4 windows aren't leaking... ttops on the other hand ... I wouldnt use urethane as if you ever had to take one out again, a glass company would have to cut it out, and it is a pain in the *ss with the studs and urethane

I just use the butyl and install the seal with frame and bolt it down. I have removed the quarter windows a few times and reused what's there without any problems...this time I removed it all to paint...

for the t-tops I'm going with these instructions...http://members.shaw.ca/gregtsmith/T-Top ... -Strip.htm

Jack,
Do not use butyl-tape on the 1/4 windows on your wagon.
Butyl is what is intended for bolt-in glass like the 1/4 windows on coupes.
The 1/4 windows on wagons need to be glued in with urethane, like a windshield.

I forgot it was a wagon... 😳
