Permatex 81173 Black Silicone Adhesive Sealant, 12.9 oz

I had a leaky sunroof (it's not draining properly and cleaning the channels repeatedly has done nothing) on my truck and have tried quite a few products already. But none of them could hold up to the Florida heat and weather, and would end up deteriorating and crumbling. I tried this product on the seal around the window and have had no leaking whatsoever. This stuff comes out like a thick black, tar-like caulking and is NOT easily cleaned from the hands or anything else you get it on, so be careful. You'll need gas or WD-40 (or something similar) to remove this stuff. Or just wear gloves, if you're messy like me. When it dries, though, it turns into a thick rubber-like seal that has elasticity and works extremely well; it is still holding up with no problems at all. Another bonus is that because it's a silicone seal, you can easily "peel" this stuff off if you ever want to remove it. Just pry up a part of the coating, and it'll all peel away in a big strip. And when I purchased this, it came as the product that is shown (with nozzle). There are also tubes of this product available, which I've used since and had no problems applying it.

I had a maddening vibrating wind noise on my L322 Range Rover. It was coming from the "scuttle" which is the decorative trim at the base of the windshield. So, I spent some time cleaning underneath it and then applied this. It worked perfectly. While I did make the cut to the applicator giving me a small diameter of product, I wish I had done the smallest diameter possible as it would have been easier to manage.

It's what you expect. Ok to manage

This caulk is easy to use. It flows nice and is good to work with. Dries hard as a rock. It sticks to anything.

Permatex speeks for itself quality product and he is good last great weathers any storm.

Good silicone and good price. I always order this.

Worked well on dealing a 22 year old yard trucks windshield. Leak stopped. Defiantly leave out in the sun to warm up before usage. Comes out easier when warm as expected.

Permatex products are generally top of the line, and this is no exception. Was looking for something to seal my foundation vents in place as the set screws were constantly loosening and then the vents were falling out in higher winds. The black color was perfect for the black vents which allowed me to seal the top and make them somewhat watertight while not standing out against the bricks. Not sure what I will do when I need to replace the vents as they are indeed stuck like glue!!! Would you expect anything else from a Permatex product that is a silicone sealant???

The sealant is unusable, its already dry

used it on my convertable top where the rear glass was coming loose.It worked great

Buena calidad. Pero aún no me han enviado mi factura, ya rebasamos el mes!

The entire tube of silicone was dry. Fully sealed, but dry and unusable.

I've used before with excellent results
