Glass shop comes tomorrow - Windshield Install
OK , my great and distinguished fellow forum members , this is the question.......
Glass shop comes out tomorrow to install the windshield in my 66 roadster.
I have cleaned the birdcage, did the rust stuff and have it all set to go.
The glass shop is bringing the windshield, (insurance claim, rock) . I want to make sure I know the correct order , I would have done it myself, but I can't physically do it. So they are sending two fellows with limited experience in gasket mounted windshields.
I have the gasket and they have the two compounds, Butyl Rubber Sealant and 3M Black Bedding and glazing compound.
Question 1 is:
Do you put the gasket on the windshield without any sealant in the glass channel,
or do you put the sealant in the channel and then put gasket on windshield.
Question 2
If gasket is put on without sealant, is sealant then put under rubber gasket when windshield is in frame.
Question 3
Once I know the answers to the above questions
I will have the glass shop put down a ribbon of the 3 M 08509 in the birdcage where the gasket will contact the cage on the front side
They will do the rope trick to set gasket in pinch welt
Once that is accomplished , we should check all areas to make sure gasket is not pinched and is in place.
We then use the bedding compound to fill any gaps that may be a way for water to get past gasket and birdcage channel, into car or inner birdcage.
I am going to put the trim back on myself. I will use the butyl tape to fill in spaces in trim between clips etc. The old caulk tape was still in place and I have taken pictures of its placement.
So....... Please let me know which of the first questions is the right procedure for the glass and gasket sealing.Comment

Re: 45 Year Old Birdcage - Windshield Install
Jack,
I am almost certain the 1963 shop manual states to install windshield then glue it to the rubber AFTER it's in the car.
The shop manual also states to put a bead in the pinchwelt channel before installing the windshield but some don't do this because it makes a mess pulling the string. After the windshield is in the car the bedding compound is used to fill the channel before re-installing the mouldings. I guess in place of the 3M compound you could use some of that gray caulk (frost king) from home depot.
Lets see what others report is the best method.

windshield install and trim update
Here are some pictures of my windshield / dash / trim install.
As you know , my windshield was broken by a rock on my trip. Pictured below is the back side of my trim. It shows the strip caulk that was used to seal water out under trim.
My car never leaked from the windshield and my birdcage as seen in other photos is almost rust free.
I believe the good use of the strip caulk kept out the water . The good use of soft bedding material that was still soft when rubber gasket was removed kept the water from passing from glass outside of cage to inside of cage in the pinch weld area.
Back of trim as removed, notice placement of black strip caulk , if it was not on trim , in was stuck on birdcage. Once continuous ribbon around all of the outside part of trim.
Notice the condition of my original clips, no rust, still green with a "p" in the center of pin
glass guys come tomorrow to put in glass, I will do the trim later
Jack
Back of trim just taken off
Good idea to mark where clips are with trial fit
ready for windshield

Re: 45 Year Old Birdcage - Windshield Install
Dick , thanks for picking that up, but it is a quote by me before I knew the right stuff. I am using 3M Bedding and Glazzing for the birdcage seal, and some flow stuff for the glass to rubber.
The 3M non Harding stick caulk is the same material used on the car over 36 years ago. No leaks.
The bedding material used was a soft mustard color putty like stuff. The 3M stuff looks just as messy.
All my clips are nos or orginial, as seen in pictures. When you have the chance to put on the trim without the window glass , you get to see how the clips work, and how to release them without problems, if not glued down.
The only part the glass shop is doing is the putting in the window and doing the rope trip. Also I will have them put a nice bead of the beading material.
They should be here in a few hours to do the work, I will post pictures later
Thanks again
Jack
PS are those factory clips from my upper trim ?Comment

Windshield Installed
I had the glass shop order the glass and all they are doing is putting the glass in the gasket and installing the window into the frame.
Brian, from Safelite, used the rope method, he laid down a bead of the 3M Bedding material that I supplied, and we picked up windshield and put it in. Two people are needed, the rope worked without any problems, he used just glass cleaner to lube channel.
The corners are difficult and take some work to get the window in the right position. I think the problem is that our cars have settled and the birdcage is not the same as it was 46 years ago. The glass is the same size.
He then put a rubber sealant between the glass and rubber.
It took no more then an hour for us to get the window in.
It took me about 3 hours to get the trim on. The new gasket is bigger then the old shrunken one , so the clips worked but I still need to work on the ends of the lower trim. I also did bend the trim a bit on my first disassemble a few months ago.
Unfortunately, that knowledge is gained at the cost of bent trim , once you have it off, you can see how easy it is to do next time.
It was raining today so it was a good day to test for leaks...
No Leaks , not from glass or top
The 3rd latch also helps, but I could not find any water in the car on the edges of glass, or kick panels .

Jack, if that's a Safelite windshield it was made in Enfield, NC, not very far from where we were. I've spent a lot of time in that facility.

Re: 45 Year Old Birdcage - Windshield Install
Jack,
If I read correct you say he put glass cleaner in the rubber weatherstrip gasket channel to lube and aid in pulling rope/rubber over pinchwelt.
Did the 3m bedding compound make a mess because you put a bead before installing the windshield?
What type of glue did they use to cement the gasket to the windshield after it was installed, do you have a brand.
Great job..

Yes , we only used glass cleaner to lube channel before we put rope in channel.
Yes, the bedding stuff is a mess, and I was temped not to put down a bead. If you use too much , it does not let the rubber channel and glass to set on pinch weld, without doing a lot of squeezing to get the bedding out of the way.
I think you could just put the window in and go back with a gun and put in bedding between frame and rubber. My car had a similar putty in the channel, so I did it before installing glass.
Maybe someone can tell us about it on the forum.
After the glass was in, he put the buytle urethane rubber flow(3M or others make it) (heat in oven before use) between the glass and rubber on the outside side of glass. This stuff is an adhesive . The bedding material and the 3M strip caulk that I used for filling gaps on birdcage is non hardening. You can see it on my early post , and how it was put on trim before trim installed.

Re: 45 Year Old Birdcage - Windshield Install
Jack,
My 63 shop manual calls for bedding compound in the channel before the windshield is installed just like what you did. When I installed the windshield on the 63, I decided not to put any bedding until the windshield was installed because I was afraid it would make a mess and keep the rubber from seating.
I was just curious if that bedding before the windshield installation was really necessary, thanks for the response.Comment

Re: 45 Year Old Birdcage - Windshield Install
Hi Don, here are the first pictures of my car , with windshield in, interior done and yes, a new wheel. After 42 years, it was time for a change. My son is 6'6" and will get the car some day. He does not fit with old wheel. Also , I have power steering and the new wheel feels great. Looks funny, but to a non beleiver, they would not know the difference. When I visit the NCRS bunch, I will bring the old one with me, for a quick switch, NCRS guys can be a tough bunch, so I am told.
Two years ago
Today plus 30,000 miles over the last year

Re: 45 Year Old Birdcage - Windshield Install
Looks fresh as a daisy Jack !
None the worse for wear after a 30,000 mile year. Yikes!
I just logged 800 in mine last weekend, and thought of your 500 mile days a couple of times as I dragged my 60 year old bones out of the driver's seat... I am still not quite sure how you did that for a solid month. You are an inspiration.Comment

Re: 45 Year Old Birdcage - Windshield Install
3 months Don, 3 months, and thank god for the forum members who kept me alive and helped my insane quest in an old car with an old body. But , I looked good.......felt terrible......but looked good,,,,,, most people never saw me try to get out of the car at the end of the day...........
Just like a car wash makes you think the car runs better
The seats, and interior fresh up , a motor that just hummms,
feels like it did more than 40 some years ago.
I guess I would lose a few points for the wheel and two tone interior..........
Tough bunch
Jack
