re-gluing in quarter windows

[pontiacgp]

I prefer to use whatever method was used on the assembly line.

I put a windshield in a '67 442 convertible a couple years ago with butyl tape, just like when it was new.

The factory used urethane for all the stationary glass on G-bodies, so that's what I go with too.

I wasn't suggesting Jack use butyl, I just looked it up, learned a few things and found it interesting...

Hi Jack, I just notice this topic. How in the world did you get the glass out? I tried saving the side glass from my Malibu wagon and they broke into a gazillion pieces as soon as I touched them.

Mark,
It was a bear. I only removed one side, but will also remove the other side as well. I used a combination of utility knives, a scraper/ putty knife, and a piano wire.. cutting the seal from the inside and then used the piano wire the rest of the way. I tried to work at it gradually. It took longer than I thought. Perhaps if I heated the tip of the scraper, it would have probably cut the seal with alot less effort. But I'll try that next go-round.
I was alittle nervous about breaking the glass, I won't deny that.

A friend of mine who was a body man back in the day told me that he used Butyl rope. And that it sticks very well. I honestly have never heard of butyl rope...tape, yes. But I'll use whatever works best. I guess it's older technology.

it's harder to remove a window that was installed with butyl.....when you pass a knife thru urethane it stays cut...butyl doesn't work like that...

Tape, rope, tomayto, tomahto... Same thing.

Ugh, no kidding...
Your best bet for removing a window that was put in with butyl is to just park it in the sun and push it out...
Otherwise you're just pissing up a rope... :lol:

I just did both of the stationary windows in my El Camino ,They were originally installed with urethane,
It took about two hours to cut them out prep & primer them and reinstall.
We had to take them out to replace the two weather strips. I had my windshield replaced at the same time.
My glass guy only uses urethane, butyl is a mess and is out dated technology.

Thanks guys!
I appreciate your input. Looks like urethane it is. The only thing that concerned me was that it originally had what looked like a formed rubber gasket with a string molded in. That appeared to be sealed with caulking.

I kept the front glass from the Malibu by cutting it with this thing. It was an experiment, and I was pleased with how it cut the old hard Butyl, only needing a quick pass with piano wire to get the stragglers.It was so cheap from Harbor Freight, I figured even if it only lasted for 1 car it was worth it.

Mark,
I thought about one of those devices. It would saved alot of work and time. I pretty used what I had available. I still have one more piece of glass to cut out. But that one is pretty loose already.
I could use it to dig out the old grout in my shower when I'm done with it.
