I have not heard illegal and if so why is it still sold?
The thing I see is how old are the "new guys" doing the glass work?
What do most of the cars & trucks they do glass on use?
Were the "new guys" ever trained on butyl me thinks not.
Now I am old school and have used butyl and to me it is easy to use. It comes in 2 maybe 3 sizes 3/8" & 1/4" that I know of.
The glue needs to have primers both on the body & glass.
I hear the glue (maybe not all) needs to be heated before you can use it, maybe to get it out of the tube.
Once open it sets up unlike butyl, cant seal the box it comes in and it is not in a plastic bag.
Just my .02
On a side note anyone know the size butyl our trucks used from the factory?

I really don't know about the illegal part or any of it really - it was just fresh on my mind since it was only a couple of days ago.
Did a quick search and looks like there are other mentions of the legality of it - with responses being that it's a crock or that it only applies to newer vehicles.
But again, nothing I have experience with or have any real interest in
As long as the glass stays in and doesn't leak, I am happy.

Both the 84 and 86 shop manuals show 2 'procedures'. One being an 'I' beam butyl kit and the other a 5/16 (8mm) round. I believe they were both the same butyl kit number though (didn't write it down in the shop before I came in).

No, Never. They went from a rubber gasket, to Urathane

Maybe the 5/16 is the 3rd size.
For back glass maybe but I can tell you BOTH of my 81 trucks use butyl on the front glass.
I would have to check but think the 60's trucks or earlier used a rubber gasket up to maybe early 70's again I would have to check as I am trying to remember what I have seen over the years.
Just checked LMC and the only rubber gasket is for the rear and vent glass. Could not find anything for front glass.

With all due respect, how/why are you arguing this? As I mentioned, even the Ford shop manuals say butyl.

After a certain year, the urethane may have been used. Possibly at different assembly plants with different vehicles.
I believe '79 and older used the rubber/trim style mount. '80 would be the first year to use BUTYL. Yes, I said it too. I've owned and parted out many, many vehicles from the 70's through the 90's. All of them used the butyl ribbon seal. How do I know this? When we pulled the glass, it's easy to cut through with the standard blade style cutter, and you get the typical "strings" hanging all over it, and it's usually still pliable. You don't get that with urethane.
I set one windshield with urethane once and forgot to use the blocks. The glass ended up too deep in the opening which caused the trim to be angled, not flat.
When I talked to my glass guy (who has been in business for quite a few years) said not to use the butyl ribbon any more. Don't know the laws, but am thinking it's to make sure the glass stays in the opening during a collision.

You should use the rubber blocks with butyl also to keep the glass from moving down over time.
As for the molding not sitting flat I would think that would have something to do with how thick the butyl was and why the different sizes.
I just don't see what the big deal is using butyl on a car or truck that came from the factory with it.
Besides if the glass popped out from a collision if I was not dead I most likely wished I was!
