Default Windshield Frame Prep

I removed the windshield mold on 1975 convertable, cleaned and primed the windshield frame. (Minor rust 3 pin size holes covered with metal epoxy frame in real nice condition). My question is the inside top of the frame, some people have stated that it should be filled with urethane. Is this a good idea or will it cause water retention?

My next question is how do you seal the seams of the top windshield molding or is it not nessary?

Hello

Check out this site from pws69 a real good read. Also check the AIM it shows where to put the sealant.

I always use the primer on the frames before painting. I have a write up on the site about this too... http://willcoxcorvette.com/repairand...lp.php?hID=306

Hope it helps you..

Hi Rodney,
A silver color sealer was used to seal the joint between the large header trim and the long thin piece of windshield trim. It continued on into the joint between the long thin piece and the a-pillar trim.
A black sealer was used in the seam between the large header trim and the 2 cast corner pieces.
Hope this helps!
Regards,
Alan

Before sealer:


After sealer: the flash makes it look like there's a lot of sealer but there's just a tiny bit.

This old thread is worth resurrecting because it's proving difficult to find much information.

What type of sealer is used in Alan's pictures above, between the top molding and the windshield trim? My 1970's windshield is, I believe, original (code NT - Jan. 1970 for a Jan. 1970 car), and there's a greyish sealer in that small gap which has come out in a couple of spots. I'd like to replace it.

Hopefully you see this Alan!

Hi B,
Here's an example of the sealer on an original car and a picture of what I used to achieve the result in the pictures in this thread.
Regards,
Alan

I bought the paint at my local craft store. It goes on like thick paint… you squeeze the tube… it sets up hard but flexible after a few hours. I used my finger to smooth it into the contours I wanted while it was still soft.
If you experiment with it a bit you'll find it's easy to work with.



Here's the sealer on an original 69.

Hi B,
Very nice to see that!
Certainly looks like the ss trim hasn't been off… is that true?
If you decide to replace the sealer that's on there now I'd be careful removing what's there and SAVE it in a little baggy.
Certain people are often curious just what that material is like!
I like the windshield logo very much too!!!
Regards,
Alan

Hi Alan,

I don't believe the trim has ever been off the car. There's no gap between the trim and the windshield itself. I've never had the trim off myself, and the windshield is very likely the original one - while it is in good shape, it has a couple of windshield wiper scrapes and other imperfections that demonstrate its age - I have no intention to replace it. The car is an early January build, and the glass code is consistent with that as well. The grey sealer runs along the gap in the same way on both sides of the car.

Much of the car appears to be as it was from the factory, though it was re-piainted in the proper colour in the 1990s (and not overly well), and the interior has been partially "restored" in the past (though with incorrect pile carpeting and deluxe-style wooden inserts in the door panels and shift plate - if I ever find the time, I'll go back to loop carpet and standard door panels). I've always thought it was a neat car. Here are a couple of pictures of a loose piece of the grey sealer:

Side:


I suspect I'll leave the remaining sealer alone and just fill in the spots where it has come out over time. The car never gets wet. Thanks.
