I have a vehicle I have been building for many years and this year I put it out in my driveway and then we had 3 days of Thunder storms and my windshield leaked , so I put this all around the windshield and replaced te rubber strip and no more leaks.

Fails in direct sunlight in car cabin, no way it's 450F. But it does seem to plug a water leak well, in direct sunlyght, outside.

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.

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.
