C1 windshield adhesive

[Ronald R.]

Can anyone recommend a sealer or adhesive for my 55? I've seen these pull out of the rubber at the top. just trying to do right the first time. thanks RDR

Re: C1 wind shield adhesive

Putting in sealer or adhesive can become a messy procedure, if you want to proceed that way. Some people put their windshields together without a sealer or adhesive with good long term results. A correct careful installation with attention to the details should give you good results.

Re: C1 wind shield adhesive

I found this on one of the tech sites, comments welcome.
A quick comentary on Johns post for the next guy doing this (I will forget by morning)the red are my notes


First thing is the find the exact center of the gasket, top and bottom, and align it with the exact center of the windshield.Get a long cloth tape like a tailer or tinknocker would use.I used a eraseable felt tipped pen and mark my center mark from top to bottom After the gasket is fully installed With the flap facing the inside to cover over the dash pad , then install the lower channel at the exact center. Then slide the windshied posts on most of the way and install the two small countersunk screws through the tabs into the little nut plates. Just start them and do not tighten them down, because you are going to need to spread the top of the posts enough to install the header. The you are going to install the header moulding and drive the posts into it until you can put the two countersunk chrome screws in on both sides. Then it is just a matter of beating it together tightly with a dead blow hammer or large rubber mallet and tighten the screws. The only place that I use dum-dum on a new installation, is to hold the little nutplates in place while I am assembling the frame.Dont waste your time as I did thinking they would stay in place by magic,Pack them im place with warmed dum dum rolled out in strips they need to be held by dum dum or they will slide all the way our once you comence whacking on the post,Then you can reach through the holes with a awl or ice pick and align the plates to get the screws started, and the dum-dum will keep the from sliding away. It is not really that hard a job, but two people makes it a lot eaiser! The second person is just to keep the gasket from popping off and the like. Doing one by yourself is a real pain! Don't be afraid to really beat on the frame with a dead blow hammer (I was afraid to whack it but I re -read your post again to make sure I did not mis understand you,and because you have given me such great advice in the past I wacked it even harder then I needed to.I figured if I am going to crack it lets crack it right away,after whacking it I had no fear of cracking the glass) to seat the channels, about the only way you will crack one of these windshields is by twisting the glass or prying on the edge with something hard. Leave the putt knives off the workbench, I did not bring the putty knife to the table,But I did bring my pick set,(everybody should own a high quaility pick set) One you get a set youll be lost with out them,I used my lubricated hook backward (sharp side facing out) to just run around the rubber to set the rubber against its mating surface. and do not even think about sticking anything metal between the glass and frame and prying.
If you need to remove the channels from the glass for any reason, use a wood block and a hammer to drive the channel back off . I use no sealant of any type, I found that this makes more mess than you can imagine! The only other place you want to seal is between the frame and the body by putting a wad of dum-dum around each mounting screw as you install the nuts and washers, to seal up the holes where the mounting studs pass through the body.
Your first one is a real pain, but the learning curve is real short!

Now if this does not make perfect sence to you now,just print it and once you get started it all make sence
John Again a sincere Thank You,Not to sound all blubery,But the education you have given me in the last 6 month or so that I have been working on this project will last me a life time,And as you know I am definatley teaching my son all of my skills. Your not just helping me through a car build you giving me an education I get to keep for life.

Re: C1 wind shield adhesive

Good advice about metal tools. I cracked a brand new windshield with a screw driver. Can you post a photo of the hook that you used and what did you use for a lubricant on the hook?

Thanks Ron. I have a good set similar to this set.

Re: C1 wind shield adhesive

I initially used some 3M gasket adhesive that had been sitting on the shelf for many years but it appeared good. It was very messy and slippery during the installation. Installed the windshield assembly on the car and the windshield pulled right out of the gasket. So, had to take it off the car, disassemble the frame from the glass, clean up the gasket and reinstall it, this time with Permatex Super Weatherstip Adhesive #81850. Clean up was easy with rubbing alcohol and the gasket bonded tight to the glass. No separation of the gasket from the glass this time. BTW, I used a "short" gasket from Corvette Rubber and it fit very well. Hope this helps.

Re: C1 wind shield adhesive

Thanks for the help, i have installed 5 C 1 windshields and all pull out when you latch the top. Mike M suggested the adhesive just needed a name! thanks again ronnie

Re: C1 wind shield adhesive

From the research I've done, any professional quality urethane adhesive should do the trick. I haven't attempted to latch mine down yet as I am still fitting the hardtop. I can say for sure that the rubber is stuck well to the glass though and will keep you posted as I latch down the top.

Re: C1 wind shield adhesive

I have restored and installed numerous C1 windshields and if done correctly the glass will not pull out of the gasket. Be sure the 2 tabs on the posts are good and even if good have new steel ones installed. I have never used any adhesive to hold the glass to the gasket. If you use some non hardening 3M sealant in the channel of the gasket it will help prevent leaks. As far as steel tools, if you touch the ground glass edge of the windshield with almost any metallic object the glass will crack, it is a awful noise to hear... Be Careful.
