Permatex81730 Flowable Silicone Windshield and Glass Sealer, 1.5 oz.

This product is perfect for resealing the leaky roof seams on my 2005 Odyssey. This is the third time I’ve had to reseal the roof seams. The other two sealers were more difficult to apply. This sealer flows well allowing for spreading and making a superior seal. I bought extra tubes to have readily available. I would expect this product is well suited for many applications where an aggressive, slightly flexible bond is required. I think this product is a very good value.

Leaking in heavy rain from behind glove compartment likely caused by windshield. My 2007 was forming puddles where passenger places feet in front. Easy to use applicator got under soft plastic lining. I squeezed some in threw in a layer of torn umbrella then squeezed in some more and covered the top with steel epoxy. There was enough there to do the driver's side caused by a sick mechanic vandal in Miami, where a lot of criminality occurs. It worked. I'll do the glove compartment side before the rainy season, and the half-used tibe is still usable. I poked a paper clip through the pointer for future use. The durability was obviously pernanent for adhesion and no more leak is possible. The job was neat, not messy. Wore rubber gloves and worked slowly and bought a second tube for return of rainy season because of its value and size was enough for about one third of winshield.

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.

2019-'23 read sliding windows are notorious for leaking...and that's a nogo because there is a lot of electronics on the back wall of cab that are vulnerable to damage from water intrusion. My Ram 1500 is a 2020 model. The dealership replaced the rear window once under warranty, and exactly 7 days after the replacement we got a hard rain and the leak was back. So, upon the advice of several in the forum I belong to, I bought a case of this permatex flowable silicone. I sealed the crap out of the rear window, third brake light (also known to leak), and the sharkfin antenna on the roof. I'm proud to say that after two high pressure carwashes and tow fairly hard rains, I am leak free thanks to this product. I do have one minor complaint, and that being, on the label it says it dries clear. It does not. It's more of a slightly milky white. It's not that noticeable if you're not looking for it, and quite honestly, I'd rather see a slight hint of sealant rather than have a leaky window. I don't blame the dealership of the installers because they are forced to abide my manufacturer installation procedure. I blame Ram/Stellantis for a faulty install procedure. It's almost like that want it to leak, so the customer will return for more repairs. I'm glad I decided to go with this silicone sealant, because as it should be, I can now leave my truck outside in the rain, or run the truck through a carwash, and not experience leakage. I have several extra tubes...but any homeowners can find a use for some silicone, so it won't go to waste. Good product.

Wasn't what I thought it was but worked for what I needed it to

did not work

The windshield used to leak, yesterday I applied the sealer. Today it poured all day and not a single drop got into the cab. It works!
