Permatex 81158 Black Silicone Adhesive Sealant, Multi Purpose adhesive Sealant, Can be applied to Variety of surfaces, Inside and Outside use 1 x 85g

great stuff, even worked well in the rain

I used this to seal around a set of aftermarket rear brake lights after my original ones let water in and ended up getting damaged. Applied a clean bead around the edges and let it cure for the full 24 hours. The day after, we had heavy rain and so far it's holding up great - no leaks and the seal feels strong. It used just over half the tube for both lights, so if you're planning a bigger job or sealing more than one area, I'd definitely recommend picking up two tubes just in case. Will update if anything changes, but so far this stuff is doing exactly what I needed.

Good adhesive

I fixed my FitBit's screen with it. The screen fell out, but after the application, it became water resistant again, so it did the job well.

Did what it supposed to do.

worked well definitely use again

Very happy

This is consistently the best product of this type to use. It isn’t cheap but this pack was crushed in transit. Whilst functional the tube needs completely reshaping before application.

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.

Good silicone and good price. I always order this.

グリルマーカーを付けるためにグリルに穴あけをして裏側の配線ごと接着、防水シーリングとして使用。一晩放置で完全に固まって3ヶ月経ってもグラ付きは無いです。効果は文句無し。ただチューブ製なので作業しているとやがて手が真っ黒になって洗い落とすのが大変になるので手袋が必須です。

Been using Permatex for several decades and this is my go to brand for most if not all automotive sealants and adhesive. This stuff works great for attaching a carbon fiber cover on my mobile antenna. It takes about an hour to lose it's tackiness and about 24 hours to be fully cured. Also keep in mind this black adhesive is messing especially when it gets on your fingers and hands. Just use WD-40 on a terry cloth to clean your hands and all of the black adhesive should comes off with little fuss. This stuff works great and it's been over 24 hours and there's no leaks even with the past two day it's been raining pretty heavy. The for money, it's great stuff to fix and repair or to fill in gaps and holes on many surfaces.

It worked really well. Good quality.
