Permatex 81173 Black Silicone Adhesive Sealant, 12.9 oz

The sealant is unusable, its already dry

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

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.

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!

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.

I've used before with excellent results
