It forms a tough, waterproof, durable, clear seal that is resistant to weather, extreme temperatures, vibration, shock and most shop chemicals. Fills surface voids and irregularities, with a temperature range of -80 degrees Fahrenheit to 450 degrees Fahrenheit. This sealer comes from a trusted line of Permatex sealants for virtually any automotive sealing application, from windshields to vinyl tops to electrical connections. These well-known general-purpose and job specific sealants are cornerstones in the Permatex line.

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.

This is a thin silicone that does seep into cracks well.I cleaned the windshield to roof seam with compressed air, brake cleaner and acid brush.I applied the silicone, letting it settle into the crack up to the windshield edge and let dry.While installing the chrome trim, I disturbed the silicone enough to come loose.After reapplying and reassembling the trim, it still leaks.Needs to adhere better.

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.

I purchased this sealant to fix a small but annoyingly persistent leak in the corner of my windscreen. With only a single application the product fixed the problem. No more wet carpets!! Very good value for money.

I recently bought an 04 Mustang and decided to change the headlights rather than restore them. A typical problem noted on replacement headlights is leakage due to poor sealing. After seeing a recommendation ro use this silicone to go over the seal on the new headlights the day before installing them I bought a tube at the same time I bought the headlights here on Amazon.The silicone works great for going over the seams of the lights. There are many areas that you need to get the sealant down into a crevice to cover the actual seam and this worked great. It oozed into place easily and was not so runny to make it difficult or messy to use. I used a liberal amount on the seams so the sealant would cover more than a little and it would sink into the visible gaps from the poor job the manufacturer did on sealing. I did the job on my counter, with no dripping (YMMV as it does ooze slowly and depending on your light, it could drip) or spilling and no strong odors. The silicone settled into place and I was able to let it set for about 30 minutes until it was tacky and no longer oozing before turning the assembly over and doing the opposite side. I let it sit overnight to cure and installed the lights the next day. While it hasn't been long, I did take it through the car wash and do not see any signs of leaks.Great stuff and cheap to ensure your automotive lamp assemblies don't leak.

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.
