How do I glue in window glass.

I need to glue in the rear side windows and vent windows in my chopped 48 Ford. I need to use something that I can "feather" out the sealer where it meets the body. What should I use,Urethane? I don't know what they used when they originally installed my glass(had to remove it to repaint the car) but it wasn't silicone. Should I use a rope type sealer to set the glass then use a "caulk" type to smooth out the edges?Or should I give up and spend the $250 the glass company wants to charge me?
Thanks in advance.

 

This stuff feathers out very nicely. I used it to install all my 1940 Ford glass 20 years ago and then feathered it smooth to the body at the rear quarter windows. Still ion great condition as when i installed the glass in 1988. NAPA sells it. Use mineral spirits as a solvent if needed. Photo is of the rear quarter window. The lighter "black" is the bead of sealant I smoothed out with my index finger. Does not harm paint.

 

Thanks for the info. Is this product available in "caulking gun type tubes".Is it urethane or butyl? Does it require a primer? I've never done any glue is glass, only the kind that uses a gasket.
I've searched the web and youtube looking for a video of this kind of install and I'm coming up empty handed. I'm surprised there is so little info out there(but then again, maybe I haven't looked in the right place).

 

I've had excellent luck with 3M window weld urethane. It's pretty much the standard for late model windshield intalls. NAPA usually sells it also.

 

Spend the $ if you got it, get it done right the first time then if by chance it leaks it's on them to fix it

 

you should be able to get window adhesive kits and the primer off ebay , they fit in the caulking guns

 

Keep in mind this product is used as a sealer between the rubber and the glass. I used it as you see in the photo between the i/4 window rubber seal and the car body. IT IS NOT what you use to for side glass. For side glass you use glass setting tape. What kind of car are you working on?

 

The car is a chopped 46 Ford sedan. The vent windows need to be glued in along with the rear side windows. The guy that chopped it for me did a miserable job on chopping the vent window frames,so I trashed them in favor of fixed windows.I've already installed the roll-ups.
All the glass was installed previously. I got t-boned by a kid who had his license 6 days(and was busy texting). I was going 50 miles an hour at the time. The car was messed up. I removed all the glass prior to body and paint work.I think it was put in with urethane, but I didn't find evidence of priming on the glass(and I assumed that to use urethane you must prime). After my insurance shortfall (someday ask me about agreed value car insurance) I am having trouble getting the car driveable again.

 

I am not familiar with the best procedure to install "fixed" glass without using the window frames, but I would think that the glass would still first be installed in a rubber seal and then glued into place.
