Re: Windshield gasket blues: Precision supplies Steele and possibly Soff Seal
 

Just read through this thread. I keep reading about using "rope cord". I have done several and never broken one (knock on wood). I use para cord and lots of dish soap. The para cord is very very strong and as thin as a cheap shoe lace...works great! *Sorry if this was already posted...

I checked your installation link and nothing about our windshields. I found out my gasket is Precision and was installed by a pro (I am a project engineer for a large glass company). Here is a pic of your installed product....
At this time this is the only major flaw on my truck. BTW my trim is OEM, any thoughts on this before I have it redone AGAIN?

Re: Windshield gasket blues: Precision supplies Steele and possibly Soff Seal
 

i got a window seal and had it professionally installed to and it leaks three times and still bunches up in corner its like they made the rubber to long ,my old one i took out was the same way leaks bad in the corner if anyone finds a better window seal let me know i dont mind paying more for a better fitting one

Re: Windshield gasket blues: Precision supplies Steele and possibly Soff Seal
 

Hi David,

As you know many factors can come into play when an install doesn't fit right. Glass, Trim, Gasket & the install itself. It's important for people to note all these aspects to try to find the right solution.

My research & development guy's son has a '68 which they replaced the weatherstrip on about 6 weeks ago. I've asked them to redo it and video the process to see if this will help any.

When my R & D guy did this install he mentioned the importance of putting the top into the opening first then the bottom, then roping it in the same manner, the top, sides and lastly the bottom.

I will update this thread once we have the new install video produced.

Re: Windshield gasket blues: Precision supplies Steele and possibly Soff Seal
 

Video would be great. I'll be doing this very soon. New precision gaskets, original trim, and after market glass. What rope do you guys use and where can I get it?

This is a standard rope-in tool that's used in the auto glass field.

We have now done the install for the windshield weatherstrip & chrome and have posted the video on our channel.

If you have any questions about the install feel free to post them.

The video makes it look easy.

Re: Windshield gasket blues: Precision supplies Steele and possibly Soff Seal
 

Now that's service. Thanks for the video.

Re: Windshield gasket blues: Precision supplies Steele and possibly Soff Seal
 

nice :metal:

Re: Windshield gasket blues: Precision supplies Steele and possibly Soff Seal
 

mine was installed by professionals also and looks like renokeens , im went out and checked and they didnt have the second layer rubber over the pinchweld im using a butter knife and fixing it , , lol

Re: Windshield gasket blues: Precision supplies Steele and possibly Soff Seal
 

Question: Was that OEM or reproduced trim used for the install?

Great help. Thank you for making the time to put that together!!

Re: Windshield gasket blues: Precision supplies Steele and possibly Soff Seal
 

The trim was actually a repo by Precision, unfortunately it can no longer be produced (long story). We had a couple of sets still around so that's what we used.

We're fortunate to have Greg on our team who has 20 years experience in the auto glass field. This is his son's truck which is why we were able to get this done. Sadly, auto glass techs (the pros) doesn't guarantee a good install as some don't have the experience necessary with these older rope in type installs, so it's important to find one that comes recommended or that has a good reputation.

Re: Windshield gasket blues: Precision supplies Steele and possibly Soff Seal
 

I'd like to see a shorter version of this made into a sticky? Maybe the video and some tips. We should keep it short and simple.

Can anyone recommend a known experienced installer in the SoCal area, eastern LA or western San Berdo counties preferred? I've called around and can't find anyone that will say they have experience with these old dogs, just that they can do it.

Re: Windshield gasket blues: Precision supplies Steele and possibly Soff Seal
 

I'd like to know as well...
My burb and PU both need windshield gasket work, and everyone around the SW Riverside county area that I have talked to refuse to touch the glass install on these trucks.

Very good instructional video BTW!

Re: Windshield gasket blues: Precision supplies Steele and possibly Soff Seal
 

The 67-72 Chevy and GMC trucks were one of two windshields I always installed from the top first. (The other was the old Jeep Wagoneer) The tight upper corners make it very difficult to get even pull on the gasket if you start at the bottom.

Re: Windshield gasket blues: Precision supplies Steele and possibly Soff Seal
 

Totally agree and think this is a key part to getting everything to seat correctly.

Re: Windshield gasket blues: Precision supplies Steele and possibly Soff Seal
 

at 16.13 after talking about the secondary lip ,the hook tool pulls the rubber next to the glass............do not do that at home .leave that trick to the pros. great job n video

Re: Windshield gasket blues: Precision supplies Steele and possibly Soff Seal
 

I'm having a different kind of problem. Last year I had a new windshield installed by safelite, with the trim. The installer was experienced and got it in without too much problem, but it was as if the windshield was a bit too narrow. The fit top and bottom seemed good, but it was loose on the sides. The gasket will slide side to side on both sides. He said it might seat in after a while, but they would cover it if it didn't. One other problem was the glass had ripples in it and seemed to be rounded from top to bottom more than the OEM glass, which was pretty flat. Safelite branded glass.

I gave it a year of driving off and on, but it never tightened up and it leaked, so I called them back. He came with another safelite windshield, but figured it would be a waste of time, so they ordered another brand for it and came back a few days later. The glass was smoother, but fit almost the same as the other one. Maybe just a bit tighter, but I can still slip my fingers under the gasket by the windshield frame post. The gasket does not bunch in the corners, it seems to fit the glass well. It just won't fit tight to the side frame posts.

Are the installers doing something wrong? Is the glass not wide enough or have enough curve back into the frame? I just don't understand. They tried 2 different gaskets, same results.

I didn't do any massaging of the windshield area in my body work. Didn't even replace rockers. I took the old glass out myself and it was a nice tight seal all around. What could be the cause of this?

Re: Windshield gasket blues: Precision supplies Steele and possibly Soff Seal
 

ask for pilkington brand .

Re: Windshield gasket blues: Precision supplies Steele and possibly Soff Seal
 

;) Idea: why don't we put a post or thread together that shows sucessful/unsecessful installs, i.e. type of gasket, trim and glass manufacture. Brief description on install: technique - top/bottom first, type of rope/cord. hook tools, sealent... Maybe we can nail down the exact ingredents to make the install work to perfection. I know mine still leaks and the percision gasket has defects. Pictures to come.

Re: Windshield gasket blues: Precision supplies Steele and possibly Soff Seal
 

Update on mine today......after 3-1/2 hours the installer is taking the glass, vinyl and trim back to their shop to WATCH THE VIDEO and see what they can learn :lol: I bet I'm going to have to do it myself to get it right. Stay tuned.

Re: Windshield gasket blues: Precision supplies Steele and possibly Soff Seal
 

Windshield (FY) + Precision gasket (71-72 w trim) + OEM 71-72 trim + top first w rope no sealant = success (<1 hr install: EASY)

* same arrangement save for repro trim (both 71-72 AND <70 with correct matching Precision gaskets) did NOT work despite four attempts by three different installers - the trim would not conform to the gasket - beware repro trim

Re: Windshield gasket blues: Precision supplies Steele and possibly Soff Seal
 

Thanks for your help ! Just ordered mine now ! Great customer service !

Re: Windshield gasket blues: Precision supplies Steele and possibly Soff Seal
 

Just one last thing that wasn't addressed in the video is bedding compound. We did not use any and have done a water test with no leakage to the weatherstrip. However it can't hurt to add a little to give more confidence for a water tight seal.
