Permatex 81730 Flowable Silicone Windshield and Glass Sealer, 1.5 oz.

Just saw this stuff on a mom’s car group and grabbed it for my husband’s old SUV that kept dripping on the passenger side whenever it rained. I’m the one juggling school drop-offs so that leak was driving me nuts. We cleaned around the windshield, I squeezed a thin line of the sealer into the tiny gap, then waited a day before driving. Next morning it poured during preschool drop-off and the floor stayed dry. That alone made me so glad I tried it. It looks clear, doesn’t scream “repair” at all, and i tossed the tube in the garage for next time. If u have a little leak starting, this is handy to have.

Fixed the issues I had with leaking rear glass on my truck! Easy to apply! Wish after drying it stays clear, but unfortunately it has light white shade (not fully transparent), but I don’t care because it fixed the leak I was fighting for a long time!

Easy fix for my shop’s drafty front door glass. I run a small print store and cold air was sneaking in along the top edge of the window by the counter. Customers sit right there to sign invoices, so that breeze was annoying. I cleaned the gap, ran a small bead of this Permatex, and let it sit overnight. Next morning it was clear and flexible, and the whistle from the wind was gone. I like that the tip is skinny so i can follow the trim line without making a mess. Used the leftover on a small chip around my truck’s windshield and that sealed up fine too. Reallly glad it stays clear.

From the package: "Specially formulated wicking action silicone. Flows into hidden and hard-to-reach leaks around glass..." I did not find that it really wicked at all. To me, it is just a more runny RTV silicone sealant. Because is thinner, it will flow somewhat into nooks better than you can squeeze normal silicone sealant yourself. This, overall, seems to contribute to a better seal, so it might be the best product for the application, but it is not anywhere as great as the description might lead you to believe. Also, because it is runny, it is better used on small gaps and where the application is horizontal. If at an angle or vertical, it will tend to run out and drip. You might be better off with two light applications based on this. Based on its performance to claims, I'd give it a bit under 4 stars. One problem that this product (and most Permatex products) has is that it comes with a cut-off nozzle to apply the sealant. After you are done, there is no way to seal up the tube. Unfortunately, this makes it more of a one-time-use product and not so good if you want/need to do multiple applications because you still have a leak and/or the product leaked/ran out. I sealed the tip up extremely well with electrical tape, and it barely lasted overnight. (I had to cut some more of the tube off). Some other products (GE, I think) have a replaceable, screw cap over a pointed nozzle which would be much better. This probably knocks it down to 3 stars since it is not that cheap and not widely available. Finally, it claims to be odor-free. While it is vastly better than the pungent smell of acetic acid, it is not odor-free, but not really bad at all. Very-low odor would be more accurate, although smell is lesser important to me, I round back up to 4 stars. See my customer image of some landscape lights I was trying to seal from irrigation spray (which keeps corroding/ruining them). You can see that it flows better into crevices, but that it also has a tendency to run out. Hope you find my review useful.

Went on easy, good flow. Was able to the top and sides of my windshield and my sunroof with one bottle. Really was having to squeeze at the end but got it all. Large SUV too, a LX470. Will update after a good rain and let y'all know how it does.

Good product Water leak on my vehicle is gone

Worked as should

This little tube works. I run a gym and bought it for a nagging drip at the top corner of the front door glass. Techs wanted a few hundred to “reseal everything.” I cleaned the channel, squeezed this into the tiny gap, let it flow for a minute, then parked the door open so it could cure. Next storm, zero water on the rubber floor. That alone made me glad. The nozzle is thin so I can run a clean bead without making a mess. It dries clear so members dont notice anything. Ill keep a tube in the office drawer for the next mystery drip.

ヘッドライトの水滴侵入対策として購入。合わせ目に流し込む感じで施工。コーキングとしては柔らかく隙間にスウッと勝手に入り込む感じでムラが出にくい気がします。施工時は半透明ですが、硬化後の方が透明に近い色で目立ちません。

Windscreen gasket/beading had come loose, poorly jnstalled and during high speed it would flap onto the roof and then if it rained I'd get drips from top of the windscreen into the car. 20 min to clean, and apply this and 2 days with no water contact. Solved the problem fully. Have driven 2000 km since, half of it in the rain and some of it in torrential rain on an expressway. Fixing it at a workshop was told they would have to unfit and refit the windscreen which depending on whether the glass broke during uninstallation would cost from 2000 to 10000. Has saved me 10000.

I received an opened item that was patched up with tape

Jag tappade över till en spruta. Silikonen var lättjobbat och flöt ut bra. Jag kommer att beställa det på nytt.

Para las personas que piensan que va a llenar una grieta, Están en un error, este tipo de silicon no es para eso, jamas va a entrar así, yo lo utilice por que mi auto un aud A1, en la parte superior de parabrisas lleva un sello que se daño con el sol y se metia el agua y humedecida el cielo del auto, limpie bien, aplique el silicon y se acoplo a todas las partes dañadas, recién han caído unos diluvios y ni gota entra. Muy contento con el producto.
