very good quality product, incredible customer service

Silicone worked great quality adhesive

Works as advertised

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.

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.

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.

I guess this product is for sealing windshield cracks or something, because it was useless in adhering my windshield to the plastic/rubber cowl of the car (from which it had separated). The packaging seems misleading in this sense.
