I have a 1996 GMC Safari van. In 2018, a rock hit my van 3 inches above the windshield seal on the driver's side, causing a dent which started a leak directly above the ignition switch inside the vehicle. I went to several auto glass repair shops and got the same diagnostic report. Replacing the windshield alone would not solve the internal leakage. I would need to have body work done to rebuild the damaged roof area first. Surprisingly, a technician who overheard what I was told by the shop manager at the last glass repair shop I visited approached me outside of his office and told me get some exterior silicone to temporarily stop the leakage without having body work done or replacing the windshield. I applied it directly to the seal, let it cure, and then I went two extra steps further. I applied two coats of Flex Seal spray over the cured silicone, and then applied two layers of white Flex Tape over the entire area - too much, in fact. This temporary fix lasted 4 years, with only an occasional small amount of leakage from the impact damaged area, which I dealt with by stuffing wads of paper towels under the panel whenever it rained hard enough to cause leakage. On May 10, 2022 , the entire internal panel area under the outer windshield started leaking - from the driver's side across to the passenger side door. I bought some Permatex 81730 Flowable Silicone Windshield and Glass Sealer, 4 cans of Flex Seal Clear, and a professional grade hybrid interior clear silicone. It took me over 3 hours to scrape off all of the previous repair tape, Flex Seal, and exterior silicone. I took a screwdriver to clear the seal area, used paper towels to drip rubbing alcohol into the seal area, waited 15 minutes, and applied three coats of the Permatex across the entire seal area, each coat at 30 minute intervals. My intention was to overdo it again by applying Flex Seal Clear over the Permatex the very next day. I never got that chance. We had severe thunderstorms in my area for four consecutive days, and two more days of heavy rainstorms after that.. I never got in my Safari for that entire week after applying the three coats of Permatex. I would look inside of it every evening, and I did not see any standing water on my rubber floormats as I had been. I pulled it out of my back yard to mow the lawn on May 22, 2022. Just as I was finishing up, another heavy rainstorm developed. I put the lawnmower away, put my van back in the yard, and just sat there in it for the duration of the rainstorm. There was no water leakage whatsoever. I intend to leave well enough alone at this point.
The right way, then there's my way. You're my kind of guy. This is my weekend project. Thanks for sharing
Thank you for making this video! It it simple and to the point, and easy to follow. It is hard to find a video to do that I’ve been looking. I haven’t done it yet but I will and hopefully it comes out as good as yours.
You sound like an astronaut with your audio setup, I keep waiting for you to say... "Houston, we have a problem"
I thought I was the only one lol
Hope you enjoyed your, flight have a nice day
😂😂😂
If you have major leaks then you will have to fill the gap and watch and wait for air bubble then hole to form where the sealant has sunk down into a crack or hole and then keep reapplying until no more bubbles or holes come back.
Excellent video! Wish every diy video were this good. Thanks!!
6 years later and still helping people thanks great vid!
Thanks. I have a 98 Z71 and we finally got some rain. Got in the truck and saw a drip. Your video has just what I needed, great job on helping people.
how did it go.>
Thanks! Looking forward to sealing up my window this way. After watching this, I feel confident that I can do it & it won't cost a fortune. Especially love the tip on using Rust Fix because I hadn't realized there was such a product & my car has a lot of rust spots, so hopefully that will slow them down.
Whoever installed the windshield for my Cobalt did a horrible job so when it rains I have water pour in when moving from a standstill. I am definitely going to try this, my original plan was some everyday silicone sealant but I will look out for a windshield sealant kit like this.
Thanks for the tips!
2 years later I'm checking in to say I also thought about standard silicone sealant and it didn't work, trying this last cheap method before the big real repair is in line
. Thanks so much. I appreciate you spending the time and giving the tips that’ll make the job easier on my 78 Dodge Aspen. Aloha
Actually the "AC Delco" touch up paint from the dealer comes in that exact same applicator; probably made by Dupli-Color. Thanks for this video though. I have a crack in my windshield and need to replace it anyways but will do so later when I have more money after Christmas. For now I bought the brand of this same sort of product that O'Reilly's sells and it seems to have fixed up my window leak (unrelated to the crack) for now. I also had a leak in the seams of my trunk and used the Permatex Black Rubber Sealant and am happy with how it seem to have worked.
Thank you, great tips! I have some spots on my 1994 Honda Civic that need touch up.
This sounds like the ticket! : )
Yep...!
Much less expensive then risking , than busting my windshield and rear window on my ( 1971 Karmann Ghia ) ....!
You got my VOTE...! First nice sunny day this is my project......🎵👍🎶
Thank you for the video this what I am going to do . You went into detail each step . 5 stars
You really should have over one million subscribers!
Thank you, I am having that same issue with my truck. Thanks so much.
@Wandaaring Diamond Butterfly; I have a 1996 GMC Safari Van, and this same issue has just developed. I will have to try this. The odd thing is that I also have a 1989 Chevy G20 Full-Size van, and I don't have any water leakage issues at all.
We got a 21-yr-old Ford and it just started leaking, this is of course what I'm going to do!
Bro!!! the best easy tutorial!! THX
Stuff works great! I have 2 lekas and thought it was the small cracks of the seam sealer in the roof. I also noticed the front shield had been repaired before and looks horrible. It's still leaking so I'll need to remove that strip completely and do it again. I was also think the second leak could be the antenna.. I guess I'm right because it still leaks after applied this on the cracks. To bad¡ Let's hope I can fix that antenna with this stuff. I tried taking out roof liner but I need to take out the complete hatch interior for that just the reach the antenna to be able to unbolt it and seal it up again. I'm gonna try masking it of super tight and lay a very thin bead of this stuff
very comprehensive. Nice work
Very good video. Very helpful. Thanks for posting.
thanks, it rained like mad today and my 2000 astro van windshield started leaking. I will try this fix .
Thank you so much! Doing on my 2003 F150 tonight.
Excellent video - thank you!
Nice job, great info
Appreciate the video! very helpful.
Thanks for the info. God bless you my friend
Good video thanks for sharing!
Good stuff man
Thanks for posting
Thank you so much it very helpful
Maybe a fingernail file could reach some of the rust closer to the windshield. My back windshield leaks really bad on my 1985 F250. I'm going to try this today.
My 96 Chev is doing the same thing. Going to do this tomorrow, thanks man
So, it's been 5 months now, how did it works for you? I'm interested in fixing my leaking truck. Thanks
@@tousshong9438 I found out that I actually had another leak as well. My truck is an extended cab, both rear windows leaked from the top, the latch doesn't pull closed right enough or the seal is old. I put those window rain gaurds on, fixed. I mean I took everything out of the truck carpet and all to find this
just used this on my 96 chevy 1500. theres a small crack from top driver side that runs towards driver side mirror. has never gotten any bigger over the years. hopefully this stuff fills in the seams and works. i even did the sides like you mentioned. do you recommend. going under the tape?
nice details.. thanks (Melb. Australia)
I think this will work on my Chevy Tahoe side panel window.👍
This may be okay if you are flipping the truck, however, if it's your precious taco that you want to keep for a long time, please pay a windshield guy around $100 to have windshield taken out and reseal with the proper urethane windshield adhesive. What you have under the windshield is not silicon, and this method may fix it for a while but it traps water on the edges or underneath and cause rust again. I got my 89' pickup and 2004 taco fixed the same way and had the same leak.
Right! Just a temporary fix to buy some time. That being said, it's still not leaking!
Hmmm, I dont save my precious tacos, I eat them😁
I paid windshield guy, and had to buy a new windshield, and the leak returned in a couple years.
I have an 04 Cavalier that the window is leaking at the top ...cause by an improper install... I may try the stuff you used
So far mine is holding up well. No leaks yet! ;)
Thank you!
Great video ! Purchased a NEW 2020 FORD TRANSIT CONNECT in Nov 2021. After the 1st car wash I noticed a few small streams of water on the inside of the glass. The PERMATEX 81730 FLOWABLE SILICONE WINDSHIELD AND GLASS SEALER, 1.5 OZ. sounds ideal to fix these leaks. I was curious how how many tubes of this did you use to go across the top of your windshield.
If memory serves me correctly, I believe I only used one tube.
My trunk is be full of water and I need to seal the little cracks around the ends to help
thank you
Thanks
Since you can not get to the rust under the seal(and considering its a small spot), could you flow something like Fluid Film (would seep into the pinholes) before the Permatex? Just a thought
Thanks bud good video explaining
Ty!!
My truck's windshield has begun to leak, I think. I just noticed water lines running down the interior of the windshield. So, will the silicone also run down the interior of the windshield? And if so, do I need to use tape to stop it? or is it thick enough that it will stay along the top? Thanks for your help.
My windshield leaked right above the review mirror, it dripped onto the dash on heavy rains. The silicone did not, so it must of been thick enough not too. It is self leveling, so damming up the ends is pretty important.
Nice video but why don't you just go ahead and fill the rest of the upper windshield so water doesn't works its way into the other areas too? If its happen there then I'm sure its effecting the areas around the too...you just can't see it since its not rusty. Thanks! I wish I have hear of this products before today. I had a leaking rear windshield too and what I did was just bought the 100% silicone and used that product instead. I'm sure works the same but I prefer the running methods where it can go and find the undetectable areas under the seal etc..
Good.
THANK YOUUUUUU
You could pour some camper roof sealant 😊
Great Video, is there any reason to paint first and put the silicone after ? I would have done the contrary....
cars are painted before windshields are installed
hmm didnt know they make patch panels for that area
How do we know if it's pinholes and not a skip. I also heard that once you use silicone you can't use an adhesion over it if it fails.
You don't know. The correct way would be to have the windshield removed and make the necessary repairs and reinstall the windshield. As for silicone, pretty much nothing wants to stick to it after it cures.
@@1D10CRACY Can the silicone be removed if it becomes necessary to install a new windshield?
@@gregb8571 Yes.
Frog tape is king!
Question - Is Rust Fix in black? How did you spray it without masking off the roof first?
Rust Fix is clear. I sprayed it down into the crack, wiped off any over spray that was on the roof and let it dry.
@@1D10CRACY Ah, thanks.
Ive got a leak and its at the bottom on the corner and the side. Will i be able to squirt this stuff upwards? as obviously gravity will make it want to run down.
it sounds like you need to have the windshield removed and resealed
Yeah, and also the metal the screen mounts to will need to be cut out and fresh metal will need to be welded in as i know its half rusted, no point popping the screen out and just bonding it back in over the rust. Just wanted something to get me through the winter, i have a tube of this now so will attempt it soon and ive got an idea how to tackle it.
Know that the silicone will make it difficult to adhere new windshield adhesive. You may be better off using windshield adhesive around the bottom edge of the windshield rather using something weird like this stuff.just a thought. Ericthecarguy has a good video on removing the windshield you might check out
Ive tried normal sealant but not had any luck with it, still leaking. Ive got a wind shield remover kit with a few different tools, its recommended to do it in warmer weather as obviously the bonding will be softer hence why i want to wait until after winter and a quick fix for now. Ive removed a bonded in wind shield before, two of us using and old bike brake cable and we got it out in one piece. If the worst comes to the worst, ive got windshield cover with my insurance anyway. :D
Did this product run through the gaps and onto the inner side of the windshield?
If it did, I wouldn't have known as the headliner blocked my view. It however did stop the leak.
@ID10CRACY - After two years, how has this repair held up? Are there any leaks? Thanks!
I sold the truck last fall, however at that time, it still had no leaks.
How long did it last? Still no more leaks?
It never did leak again, but I sold the truck a year or two after I did this.
I saw where they said don't use silicone because it expands with weather temps.
Could be, but I haven't had any issues. Ohio Weather, so we get a good swing of temps. I would say not to use it because it isn't a "professional" fix, but again, a fix like this should be considered temporary anyhow.
how runny is it? because i have to run a bead that is fairly vertical
This is going to be very hard to explain. It has a fairly thick viscosity, maybe half of what silicone has. The main issue is it has a self leveling consistancy. To explain this as best as I can, after I initially ran a bead accross the top of the windshield, it looked great, but after 10 or 15 mins, it oozed out the edges of the window where I mentioned I had to build damns. I wonder if maybe you could glue it, then place tape over the top until it sets up. Or use a heat gun to try to get it to skin over.
in a way, the ooziness is good for the little nooks & crannies of the tail light. But, i had to resort to plain silicone since i did not want to risk botching the job.
The ordinary silicone did leave a nice even bead...We'll see in the next rainstorm how well it really worked.
Thank's for the tip! :)
My Gosh. Without getting deleted, I will give you a positive note on the products in which your using. Let me help everyone here with some knowledge. 1. The rust you see at the top of the molding along the body was formed by the windshield being replaced. The installers mistake was that he did not use a primer on the scratches he caused, thus the creation of rust. What your seeing is that the windshield in that area has dis-bonded from the pinchweld of the car. Thus the leakage. The application of silicone your using should be back filled inside the vehicle below the head liner, and inside the pinchweld, not outside the car, as I am sure this thing still leaked. I should do a video on this one day.
I really need to do a follow-up video as well, as I said in the video this is not the correct way to repair this leak and silicone is not the correct sealant to use. However for a quick and cheap temporary fix, it has worked well and is not leaking as of yet. The correct way would be to remove the windshield and repair the rust. The silicone was applied exactly per the manufacturer, and is designed to "ooze" into any pinholes that may have been causing the leak. Again, a quick fix to resolve the problem temporarily, the exact purpose of this video.
I've heard not to use silicone to seal windows because it expands and contracts with temperature change. Have you had any issues with leaks since applying this?
None at all. However I wouldn't use regular silicone, the stuff I used was specifically designed to use on leaky windshields and the best way I can describe, self leveling and runny.
@@1D10CRACY thanks for sharing. This problem just started when it rained earlier. God bless you.
Thanks so much for helping so many people. I was just going to put household silicone on it.
Heading down the the zone to buy permatex and maybe a precious taco along rhe way.
On the Permatex Windshield and Glass Sealant instructions it suggests avoiding skin contact. I guess you survived the skin contact without consequences. I'm going to wear disposable gloves, just in case.
:) Probably best to wear gloves.
I would DEF put some mineral oil (there may be a better oil... idk) across the whole rust prone windshield gap. do it well before you use silicone. seal the oil in there to slow rust even more.
Then you risk the silicone not sticking. Remember, this is a temporary fix, it will eventually need fixed the correct way.
@@1D10CRACY then use oil on the rest of area that isnt rusted yet
does this glue have bad smell?
You noticed water inside your cab... _where inside_ did you notice the most water pooling???
Driver side floor.
1D10CRACY thanks
How long did it last
I don't really know. It lasted for about the year I kept it, but I eventually sold it because I had purchased another truck.
Ok thanks
Chevy design flaw?
It’s called tolerances.
1/8”, 1/16, or 1/32”.
Your best guess at Chevrolets tolerance for tolerances?
How ‘bout “ this:
“ good enuf for who it’s for?
Good enuf for who it’s for.
Great video...however, I have a HONDA and if you put painter's tape on a HONDA, the original paint peels right off!!! Then it matches the areas where the paint has already fallen off. Gotta love Honda. After four Hondas, I'm never buying one again.
Don’t use this method I did it on my 92S 10 that was leaking at the windshield and the silicone only lasted four months
It is a crap shoot and temporary as I said in the video. Mine is still not leaking.
@@1D10CRACY im glad it worked for you buddy, i think the sun deteriorated mine. it flakes off now. I got flex seal drying in the drive way right now wish me luck
thats gonna piss off the guy who will be removing the windshield later. I wouldnt do this on a collectible car, body shop guy will be pissed off dealing with silicone in the rusty areas he has to fix
If he gets pissed, find a new body or window guy! They make rubber eraser wheels that remove silicone very quickly, Safelite uses them all the time to clean up the edge. If I couldn't get to the repair quickly and had a collectable car, I would do it in a heart beat! Keeping the water out would be way more important! A temporary fix for sure, but it will buy time until you could go back and do it right.
@@1D10CRACY runny silicone buried in rust holes will leave a mess... if rust is starting... prevent any rust in the first place with oil.
If you ever need to replace it you just made it twice as hard for a glass man
They will have to use the rubber wheel for sure! I'll probably replace this one if it ever needs it. This was supposed to be a temporary fix.
How does this make it hard for the windshield repair guy? Thanks
@@technicalitems731 Silicone can be tricky to remove and if you don't remove it all it will cause body work and paint issues. We tackle this issue a lot in the RV industry and once you know how to remove it, it's really not an issue. A rubber wheel eraser will remove most of it, but then you really need to use a silicone dissolver after that to clean up the area. Ambro-Sol makes a good one that works exceptionally well. What David was overlooking was this truck needed the windshield channel cut out and replaced, a simple windshield reinstall or replacement would not have fixed the issue. Form my perspective, I felt this would be a quick temporary fix buying some time so I could address it later. To my surprise it lasted for years with no leaks. I eventually passed the truck onto another fellow and I would guess by now, the truck has reached end of life. The truck spent it's life in the rustbelt. ;) As I said in the video, it's not the "correct fix", but if you have a beater and you need a quick fix or just need to buy some time before you fix it right, this trick works.
Half of the video seems more of an advert for dupli-color when he should have been discussing the permatex sealant instead
LOL I did get a little excited over the duplicolor pen! But removing and preventing future rust is a very important step in the repair. Maybe duplicolor should sponsor my videos! ;)
@@1D10CRACY I just got a duplicolor pen, loved every bit of show and tell about the pen
How to quickly ensure your pinch weld continues to rust*
The correct way would be to pull the windshield and fix it. But as I said in the video, this is a great temporary fix. It lasted until I got rid of the truck and the current owner isn't have any issues as of yet. My guess is the stop rust stopped or slowed down any rust that was in the channel.
Thanks
