The windshield on our 66 Custom Cab leaks pretty bad in a few spots at the bottom near the dash. The windshield itself is perfect, no chips or scratches, and even the seal looks fairly new, like it’s been replaced in the last 5 years or so. However you can see a ton of globbed up glue in the corners and all around the seal on both the inside and outside. I’m guessing whoever replaced the seal either didn’t know what they were doing, or were trying to overcompensate to fix a leak, but either way they went way overboard with the glue. And it looks like clear snotty craft glue like you used when you were a kid in elementary school, so I’m guessing it’s not even windshield sealant.

So I contacted a local body/restoration shop that specializes in Mustangs, and they quoted around $175 labor to replace the seal, if I supply it. I thought this was a fair quote, however they did state that they will not guarantee the work in terms of eliminating the leak, which I also understand.

So I have some questions:

I thought I read somewhere that not all windshield seals were created equal, and that there was one specific vendor that most people recommend, I thought it might have been DC but now I can’t recall

i thought I also read somewhere that you’re not supposed to use any glue. The shop specifically stated that they would use some kind of sealant, I forget what it was exactly

and lastly, in the worst case scenario if something happens and the windshield is damaged, are these windshields reproduced? I’m wondering if I should just leave well enough alone and live with the leaks if it’s gonna cost me around 200 bucks and the work isn’t even guaranteed, and if the windshield is damaged am I totally screwed?

thanks

 

Dennis Carpenter for the seal. If you still have the stainless trim make sure you get the one made for the trim. Windshields are reproduced. I just paid $135 for a new one, made in China but fit fine. My brother and I installed back window and windshield in my truck a few weeks ago, took about 3 hrs.

 

So this is the one I want to get then, with the channel for the trim? https://www.dennis-carpenter.com/tru...iABEgI3V_D_BwE

 

I had one replaced a couple years ago and the company, obviously didn't use any sealer. I got tired of having them try and make it good. I'm going to do it myself and will definately use a sealer. Every time it rains, I get water leaking out between the glass and the seal, at the lower corners.

 

The windshield rubber from Carpenter comes with instructions for installation. The sealant specified by Ford in the Body/Interior Assembly manual is ESB-M4G31-A used around the entire perimeter of the glass channel and the windshield opening. This is a strip type calk that everybody used to call dumb-dumb. 3M still makes it but it is a PITA to use. This is a much easier to use calk and it cleans up easily with mineral spirits. And it won't glue the windshield in like urethane type sealants. 3M™ Auto Bedding and Glazing Compound | 3M United States

 

That is the one if you have the stainless trim.
