Getting ready to glue in the rear window gasket in my '68 coupe. So do you apply the cement to the gasket, the window edge or a thin film on both?

I treated mine like any other weather strip. Glue on both sides.

Hi R,
I think it's a good idea to tape the gasket in place and glue it in place in sections… maybe 3 or 4 sections.

You need to use caution because it's easy to stretch the weatherstrip as you apply it and you end up with what seems to be too much strip.

I installed it across the top and just past the upper corners, and then did the lower part in 2 stages.

Some original cars are seen with screws in the upper corners… they really help hold the strip in place while you're installing it.
You can look at the holes in the fiberglass to see if they were used on your car.

Regards,

Thanks to both for your help. I like the idea of doing the top and then the bottom. That has to help keep from getting the glue in places you don't want it. Alan, did you install the window and clamp it in to help squeeze the weatherstrip in place as it set up? Also, do you have more photos? I saw you had posted some on a similar post a few years ago was not able to view them.

Also, I checked for those holes you mentioned and found them with the screws still there. Here is what the originals looked like....

Hi 68,
Perhaps these will help?.

The left corner.


The lower corners.

Mine did not have the screws that Alan pictured. It does now. I used two pieces of wire to hang the top of the weatherstrip at the top while I started working at the bottom. I started about 3 inches up the side from the bottom corner and worked across the bottom and up the other side. Then worked both sides up to the screw areas. Then finally across the top. I put adhesive on the frame, then the weatherstrip, waited a minute and started putting it in place. The wife helped by holding the glued weatherstrip in place while I shot the three screws in each top corner. Two extra hands are handy. Six would be too many.

Hi 68,
"Alan, did you install the window and clamp it in to help squeeze the weatherstrip in place as it set up?"

No, I didn't.
I was afraid too much pressure from installing the rear glass might squeeze the rubber seal out of position before the glue was completely dry.
I used blue tape on it over night.
The next day I adjusted the latches and pegs so they would be loose and installed the glass.
I increased the pressure over the next couple of days and called it done.

Yet again this sounds like excellent advice. I was worried that squeezing it before it sets might push it out of place or distort it too. However, I have seen and heard recommendations to do that. I particularly like the idea of setting the latches loose and then sneaking up on a tight fit.

Thanks again!
