Title: Back glass weatherstripping
Post by: tholt on October 20, 2019, 03:19:22 PM
Hi
I have a 1969 Mustang Mach 1. I need to pull the back glass out to replace the headliner. I am looking to see who sells the best fitting rear glass weather-stripping and rear sail panels. As I have heard there are several different manufactures for these.
Thanks.

Aftermarket rear glass weatherstripping is ill fitting.
Do everything you can to save your original, or better yet leave it undisturbed.
I still have the original in my car, so they do certainly last.
Saw a 69 Shelby at Barrett Jackson a few years ago with repro rear glass weatherstripping.
The trim wouldn't fit over it right and was beat from mallet attempts.
What a shame for a car that sold for 99K IIRC, it was a rare kind of dove grey color too.

I had a headliner replaced on a 66 Mustang Fastback without removal of the front glass. It's a similar situation as yours. The guy that did this worked at the San Jose plant repairing headliners. He trimmed the new headliner, applied cement, and "tucked" the edge under the gasket. He did the same to the rear gasket although a 66 Fastback has a trim piece covering that area.
In other words, it can be done. I sat in the car (seats removed) watching an artist at work.

Have not experienced myself but have seen postings and discussions on other sites. Some shops have resorted to shaving the reproduction gaskets down to make room for the trim to sit as it originally did in some sections. Looked but could not find those threads to share with you at the moment

I recently helped a friend shave these on a 67 GT 350.  Not fun at all.

Hi
I was afraid of that. Thanks for the replies.

I still have my original weather stripping for my 1970 Mach 1, its still on the glass (removed from the car) and in good shape but is covered with black sealing chalking. What would be the best way to clean/remove the chalking from the weather stripping without damaging it? Any help would be appreciated, thanks.

i would try using mineral spirits on the caulking.

okay, but can you be a little more specific regarding mineral spirits?

Sorry not asking about quantity and where, I am talking about type, is it actually call mineral spirits or paint thinner, or varsol, or what?

Be careful. Solvents can adversely affect the rubber. It's old.

i would have suggested lacquer thinner but the spirits are much milder. i don't think he will have a problem. 3M also makes a weatherstrip adhesive remover that i have used successfully but i do not have the p/n handy.

Thanks for the additional input, yes I am very concerned about damaging the original rubber seal. I have a repro but have not even tried installing it since I read the earlier parts of this thread regarding the fact that the repros are pretty much useless. Ironically I removed the back glass over ten years ago and only kept the rubber seal on it to protect the glass, now lucky I kept it. Thanks again for the support.
