TTop frame to window trim sealer

What do I use? Looks like there is a white hard sealer on top of a gray window putty. I need to get the old crap out since it is cracking...what should I put in there?

SMYDA might have a better suggestion, but I would use 3M Strip Caulk, #08578

Seems like a good product. Oreilly carries it. Looks like it can also be used for other areas where you don't want a silicone or hard sealer...

Looks to me like someone was repairing a waterleak.
Reason I say this is........take a look at our '81.
Notice there is NO extra sealer anywhere.



Here's some options:

First clean all that white stuff (crap) out of there.
Then you can run a thin bead of Windshield Urethane around the perimeter of the
glass. ( see RED arrow ) Just enough to make a seal between the glass and frame (NEATLY).
You can use a plastic table knife to spread the urethane.
Allow the urethane to dry completely before reinstalling the moldings.
(You do not want to "glue" the moldings on.)



Since you have done a fabulous job on restoring your car I would take this
approach if there is any chance of a waterleak.

Remove the glass and completely clean the windshield frame and glass.
Reinstall the glass..........BUT.....not with the original Butal Tape kits.
Instead use the modern High Viscosity Urethane. Prime the Frame and
glass with Windshield Pinchweld Primer and lay a bead of urethane the size
of your index finger and install the glass. When the urethane is completely
cured (24hrs) the windshield will be a structural part of the bird cage.
(Provided everything is done properly)



JUST A NOTE: If you were to install a windshield in a modern car with passenger side air bag
with the old BUTAL TAPE kits.... when that air bag deployed it would blow the glass right out
of the car. In fact .... even though the driver bag does not touch the glass it probably
creates enough cabin pressure upon deployment to blow the glass out as well.

What's in the notes? SMYDA is right, there is absolutely no sealant used there. I fear your w/s frame is leaking (rusted) too.

"A" says "strip sealer,one per job." Looks like it is at the back of the halo.:confused2:

OK..... I just read the question again you sent me this morning.
Now I know what your asking.
We're talking about two different things.

The strip caulking your referring to was used under the T-Top Bar "Chrome"
trim to prevent water from leaking into the passenger compartment from the
Trim area.....not windshield.

Here are a few more pics of our '81.

You can still see the original strip caulking at the rear of the T-Top Bar trim.
(which is held upside down in the photo).



Note here the grooves made into this part. (pointed at by screwdriver)
This is what is being sealed to prevent a waterleak.




At the front by the windshield, strip caulk is used where the trim meets and around the screws.
Butal Tape or Strip Caulk would work fine for these areas.
I would NOT use urethane here.......If the trim ever needed to be removed
again you would probably destroy it trying to get it off.






From what I see in "SmokinBBC" pic it appears the white sealant is placed at the glass itself.
Hopefully his Windshield Moldings are not glued on.

Hate to dissagree with you. The AIM for the '70 shows that bead type sealant was used in that area....I think:amazed:. Check view A and view C in the first pic....shows 1/8 diameter bead.

Looks like a lot of bead sealer was used up there as well as a caulking strip.

Well.....that's what we get for comparing an '80-'82 to a '70. :clobbered:

I still say TT and I are both RIGHT in regards to the later C3s.
My car is proof of that.

Now we just have to figure out what exactly they used in 1970.
Does it have to be NCRS correct or just functional???????

Get that trim off and snap a few pics so we all can get a look. :bounce:

Can't argue with proof!

Not NCRS...just functional.

All the trim fits so nicely, I shudder at the thought of taking it off right now and possibly getting into a bigger job. I was thinking of using the 3M strips that Jeff came up with to get me through the summer.....I need to drive this beast for a while!

Next winter when I am redoing the interior, I was planning on Pulling the ttop molding off so that I could buff/polish it. From the looks of it, it might be the best time to remove the windshield trim and reseal everything up.

BTW, butal was used between the trim and windshield....definitely not glued on.
