The Butyl tape Nacho showed is correct. However, Urethane is the modern way of doing things. A glass company warrantying their work may refuse a job with Butyl. My last glass install...I ran into problems trying to use the Butyl tape. Apparently my front window channel is not perfectly square...... So, the glass would not lay perfectly flat all the way around.
The car was wrecked and repaired previously to include one frame rail and core support.
I had glass company come out and Urethane it in. If you go this route.....Make sure they put the trim back on too... If they put too thick/deep application of the Urethane, it could effect trim installation.

Have some doubts. This topic floated on on Moparts too and I have read lot of pp, spelling butyl but related to diff products.
The "tape" or "rope" is what 3M calls ribbon sealer, which is kinda a clay shaped as a ribbon, hence called ribbon sealer.
Then the window chanel is filled with the non hardening/curing filler that I have read that is what is actually called Butyl?
On my car I used last time Urethane in place of the ribbon, installed the glass waited ro dry then filled the channel with this non hardening seale applied with the pump or gun. On the previous job had used the ribbon sealer and also the Butyl? Like factory did, or at least like I found on my car the first time glasses were removed.

By the texture on pic This is the filler I meant... being used on a windshield gasket assembly, not ribbon sealer assembly, but same product Since doesn't cure somehow allways flows everywhere is needed and you can clean the excess anytime.

I see a mustang windshield gasket :-) they need plenty of window sealer..
when you install your charger windshield with modern urethane adhesive,i recommend to use the small foam tapes that usually comes with a new windshield. so you have the correct hight of the glass when installing the trim. without,the windshield maybe tend to sink in because of their own weight. it also prevents excessive adhesive from penetrating into the inside of the car.

That's a good way to go. Sounds like it replicates the factory rope-seal method. Glued in is definitely more secure. The channel shouldn't be filled-in like the mustang's there though. Need to keep it as clear from sealer as possible to allow water to drain out of it and dry. Sealer and/or tape should only be to the edge of the glass. Mine built up dirt and debris over time, like they all do, down in the corner of the back window. Then it rotted. Only a few pin holes in 40+ years though. I was lucky.

I can't certify if the filler must be applied or not but my car got it factory and I can't imagine not using it, specially with vinyl top, where the vinyl can get storaged the water hence the moisture. The filler is a must this case if you ask me.
The small "foam" tapes which I found on my car were rubber blocks are a must on urethane and also ribbon the same.

specially on the Mustang windshield gasket its a must to seal it like on the Picture. otherwise you have a bad water leak in yor car...
The foam tape wich i mean,is at the inner edge with about 1 centimeter distance to the edge around the whole windshield. that 1 centimeter leaves enough space to apply the urethane on the glass. and like nacho said the rubber blocks can also be used.

That's to be expected. That looks worse is some places than mine, and a whole lot better in others. Did they use POR-15? Anyways they did a great job. That should take care of it! Peace of mind that it won't be sitting there getting worse. It holds a lot of moisture for a long time, after a car wash for instance, before drying out. Accumulated dirt and pine needles etc. made mine rust. Now its a nice dry channel.

Yes, they used POR-15. And I saw the car after they removed the rust but before applying the POR-15. They also polished the window molding while it was off the car. I use a gas leaf blower to do the overall drying after I wash the car. Then I use an airhose with power nozzle to get the water out of the window and door moldings, as well as mirrors, trunk lip drip channel and around the hood.
