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

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.

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.

Being someone who often tackles small car repairs, i found this Permatex silicone sealant to be quite helpful. it works well on cracked or leaking windshield edges when i'm on the go. the flowable formula makes application easy and smooth. i appreciate having a reliable, durable option in my toolbox for those unexpected windshield situations. it’s a solid choice for anyone who needs a quick, dependable fix while traveling or in the garage.

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.

I used this product to re-seal the front and rear windows on my 25 year old Ranger pickup. I had previously used clear silicone that was for windows and bathrooms, but the windows still leaked. After removing all old silicone from under the edge of the black rubber window seals, I applied this product. One tube was sufficient to do both windows. After several heavy rains, I have found no leaks! This product works as advertised and is better than any other silicone sealer that I had tried.

Bought this to fix a tiny but annoying leak along the top edge of our minivan windshield. During heavy rain the water would drip right onto the dash and my daughter’s coloring books. First I cleaned the glass and trim really well, then squeezed this right into the hairline gap. It’s thin enough to run into the crack, but not so runny that it goes everywhere. I let it sit overnight and the next day we drove through one of those nonstop spring storms. No leak at all. I was so glad i didn’t have to drag both kids to a glass shop, and the tube still has plenty left for the bathroom window.

Didn't really work for my application. Maybe suited for others.

I had a very big leak in the seal around my windshield that flowed water into the interior when it rained. I squeezed this all along the crack above the top weather strip, and now there are no leaks. Completely surprised it worked so well and in only 1 application. I assumed it would leak and I would need to apply a second time at least, but this stuff is pretty amazing. I'm going to use it for other stubborn leaks as well. Well worth the money.

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.

An meine Frontscheibe ließ Wasser durch. Die Werkstatt, meinte der Kleber ist durch und man muss die ganze Scheibe rausnehmen, säubern und neu verkleben. Kostenfaktor in der Werkstatt 1000€ Dank gründlichen Recherche, bin ich auf Permatex gestoßen. Gekauft und angewendet, kaputt machen konnte ich nichts, war ja schon kaputt. Um so mehr bin ich von Permatex begeistert. Die Anwendung verlief erst mal einfach, das Zeug floss wirklich in die kleinste Ritze. Mein Fehler war, ich hatte keine Handschuhe angezogen, so klebte das Zeug nicht nur da wo es sollte, sonder auch an meinen Fingern. Habe es erst mit Aceton von den Finger wegbekommen. Das gut, mein Auto ist seitdem trocken und das erspartes Geld konnte ich wieder woanders wie z.b. by Amazon ausgeben Kann es nur empfehlen

Really good stuff, had a leak on my windscreen,cleaned area with brush and cloth and an acetate cleaner.It rained heavily an hour and a half later and no water came in so would recommend.
