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

I'm in the same boat. Started out with a gasket and trim from LMC...yea, I know..seemed like a good idea at the time. This is the short leg version of the trim and a new windshield. The install was handled by the body shop so I wasn't there. After a couple hours the glass man gave up and said he would provide his own gasket for $85 and be back the next day.
Well, when I picked the truck up I noticed the trim wasn't seated all the way at the top driver's corner and pointed it out to my body man and he said after I get it running he would deal with it. It took a while but now the inside upper corners are wrinkled on both sides.
Since the body shop set up the install and the installer provided his own gasket they will sort it out and it won't cost me any more $$. Seeing this thread I thought I'd post some pics before they fix it.
This truck is way too nice to have flaws like this so I will be there the next time they work on it...they better bring their lunch cause they're not leaving till it is right.

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

That's exactly what my gasket looked like before the recent "fix (my top trim piece isn't yet installed)." I could easily peel the inner margin away from the pinch weld. It leaked like a sieve.

If you can, consider buffing an OEM set of trim to install in place of the LMC stuff. That's the next step I'm going to try. Good luck!

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

What about lubricating the seal where the trim seats, before attempting to press the trim in. Would that work?

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

We have installed several windshields over the years. We even run specials on glass once in a while to drum up business. We have done them with or without moldings, 67-70 or 71-72s. The ones with the moldings can be a pain once in a while, but we haven't ever not got the job done. It is always my glass guy and me when there are moldings involved, but without moldings he will slip the glass in sometimes while I invoice the customer...lol Precision is the brand we sell and use. PPG or Pilkington is the glass. We will probably be holding another special befor Christmas so if anyone wants one email me. We only do this on Saturdays, because that is when I can get my glass guy to come over. WES

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

That doesn't seem to be the problem - it's more like a poor fit.

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

Wes - Is this with repro trim, OEM, or both? Next time you install repro trim film the process and post it to You Tube to save idiots like me time and money :)

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

Have you attempted it?

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

All attempts on my truck were done with some type of lube. I've been present when three different installers collectively used 1) WD40 2) KY jelly 2) Soapy water

The last and best install went in easily with soapy water. The KY was too slippery!

Even with the glass on a bench and the gasket in place it's obvious that trim isn't going to sit nice let alone when you try the install. It just pops out.

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

Both. Repro trim can give us trouble, but we get it done. We have found problems with inconstancies in the dementions of the glass. I suspect that some of the problems experienced may have that problem. WES

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

A few months ago I had to redo the top on my truck.I wound up ordering a few parts from LMC,needless to say windeheild strip was one of them,mine bunched just like that,That was using the original trim also.
I called LMC back told them the problem and they sent another one no charge and they girl said they would have R&D to look into it.they tried to make out that i was the only one having this problem.2 reinstalls later and still the same if not worst problem yet.I've talked to WES and needless to say i won't never order from LMC anymore.Rubber wasn't wasn't to only problem i've had with their parts.It took 3 trys for a good power steering boxes to get one good one.
I've talked to WES a couple of times about my problems and he explained a few things to me. Get LMC to do that.yea right.I know where my parts will come from now. yae wes ,i'm about 2400 miles from you but you will talk to your customers.thanks jason

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

This is not the thread i wanted to open up first thing in the morning!!!

I HAVE to get my windshield replaced before February for inspection. Since i dont have the trim, hopefully it goes pretty smooth.

Will have to see if there is a safelite around here......

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

Be sure and use a Precision gasket. We have them in the rubber and weatherstrip section of our website. WES
Thanks, Jason. I have been down the road of poor parts too many times to sell them. I try to sort through them, and sell the best quality. I personaly do most of our R&D. We have 2 trucks in our shop, just sent one out for paint, and have 2 more waiting to come in. This is how I weed out bad parts. Helping you guys through your difficulties is just a part of our customer service. WES

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

I had the windshield replaced on my '72 Cheyenne Super 10 (with trim) a couple of months ago using a Steele gasket. The glass shop injected sealant all the way around under the exposed lip on the outside of the glass as well as in the track that fits to the pinch weld. When installed, the gasket fit perfectly to the body, and I mean absolutely perfectly - no puckering, no stretching. And there were no leaks. Now there are leaks all along the bottom. The water is getting in around the glass, not the body.

I brought the truck back to the glass shop today and they figured out the sealant under the lip was no longer stuck to the Steele gasket, but was still stuck to the windshield. He suggested smearing a thin line of sealant around the gasket on the outside claiming I will barely see it. I'm not thrilled with that idea, as it seems half-assed and not stock, but more importantly, I'm still wondering why the sealant let go of the rubber and what should/could have been done differently? Did the rubber have some kind of coating on it? Is it too late to use a different sealant under the rubber if it can be cleaned properly with the glass in place? What should it be cleaned with? I hate to start over with such a nice fit.

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

I used a precision gasket with an OEM windshield, and here in rainy washington it started leaking around the the window as well. So I put a thin bead of the highest quality clear sealant around the perimeter of the gasket... both edges. You can't tell it's there unless you look really close because I kept the bead about the width of a pen nub. No leaks.

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

That's encouraging. Thanks. Still wondering about the details as this is clearly not how leaks were intended to be stopped.

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

I was under the impression that leaks were expected by GM. They designed drain holes in the corners of the dash where it meets the bottom edge of the windshield.

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

GM used a white sealant on the bottom and up the sides 6-8" and black butyl at the top outside on the flange. That's why original windshields didn't leak. The drain holes are for water that gets in the cowl area.

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

I had mine replaced last summer with a Precision seal with no problems. Most installs nowadays are urethane glue ins so it's important to get an experience tech who knows how to do these older style jobs.

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

Keith, did you ever get anymore info about this? I should try it.

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

VICTORY!!!!!!

With OEM 71-72 windshield trim and a new matching Precision gasket the install was completed IN UNDER ONE HOUR with no difficulty.

My recommendation: Use OEM windshield trim and DO NOT waste $$$ on repro trim.

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

What do you mean by this? "new matching Precision gasket"

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

Means we cut the existing Precision gasket to spare possible windshield damage and replaced that gasket with a new Precision gasket correct for 71-72 trim. There are two possible gaskets for use with windshield trim: one for the shallow 71-72 trim style and a second for the deep 70 and earlier trim style.

deadhead, i was just going to tell you i have 67-70 trim sittin in my garage if you needed it but you got it installed.....good for you!!!

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

Thanks Mike! If you need similar work go see Sean at Lomas Auto Glass..he went the extra mile for me where other glass guys flaked. Pete

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

Okay, still at a loss - why do you mention OEM? Precision isn't the OEM.

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

No prob - The trim I used this time is OEM (used General Motors) but the gasket is new from Precision correct for the trim style (year), which in this case was 71-72 (rather than the 70 and earlier).

Reproduction trim is, in my experience, a total waste of money so go with good used OEM windshield trim when you can but be sure to get the gasket that fits whatever year trim you use.

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

Ah, I wasn't reading it right. Thanks. I have my OEM chrome trim still, and learned, as others have mentioned, 71-72 chrome trim is smaller than earlier models - requiring a specific windshield gasket.

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

The Precision weatherstrip seals have been in the auto glass market for years, almost 2 decades in fact and the only issues I've dealt with in regards to customers are #1, the customer trying to use aftermarket trim and #2, ordering the wrong seal for the trim they have, shallow versus deep set trim.

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

Great to hear, thanks for joining the discussion. Nice to hear the positive comments since I have both windshield and door Precision gaskets yet to install.

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

No Problem. Nice job on the truck... and the shop!

Thanks d, more pics just added.

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

Mr Precision, Glad you could join us in this endeavor to find the best WS gasket for our 67-72 trucks. Most of us hobbiest/truck builders find the Precision gaskets to be superior than the competition (besides OE). Saying that we are still experiencing a lot of difficulty installing your WS gasket with deluxe trim. Over the years, I seen a few installed without much imperfection, but the majority of the time, the trim pops out or upper ends are crinkled at the inside top corners (main issue). Not much fun having water drip like crazy while driving thru a Florida thunder storm. Another, is water behind the gasket and rust forming after a period of time. Not sure how your company conducts research, but if you look on these boards, you will realize there is a problem with a lot of folks and shops having the same issue. In your companies technical opinion, could you explain what could cause these issues and suggest a solution.

Thank You

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

On a different but related note: I'd like to advocate for better vent window seals. The aftermarket vent seals I installed (unsure of brand) began to crack in less than 6 months. It's a lot of work to redo the vent windows just to have the rubber breakdown that fast. The factory seals get stiff but don't seem to crack. If Precision can manufacture vent seals from a rubber compound similar to the windshield gasket maybe that would solve the problem and win a lot of customers. Thanks, Pete

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...

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

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.

Derek

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?
