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

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.

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.

worked well definitely use again

Good adhesive

Did what it supposed to do.

Very happy

Used to mend a car door seal and did a reasonable job

it's good but it's too little.

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.

I wanted to wait a while after applying this to my car before leaving a review. It’s been a few months now, and I originally noticed water seeping in through the rear window because of wear and tear on the rubber seal. I was skeptical at first since this product was so inexpensive, but I’m genuinely impressed with how well it sealed the gap. I live in an area where it rains about 80% of the year, and this product has held up perfectly. Two big thumbs up from me!

It worked really well. Good quality.

No es exageración. Un apretón (de acuerdo a las instrucciones y si no puedes ver algún video tutorial por si dudas de cómo aplicarlo, yo dudé) y comienza la magia. Es un polvito negro muy fino por lo que guantes o una limpieza de manos a conciencia es recomendable. Las chapas y cerraduras con problemas de que la llave no entra a la primera, se debe aplicar fuerza o rechina simplemente comienzan a desaparecer al paso de la primer aplicación. Yo juegué un poco con las llaves (meter, sacar, meter, sacar, girar) un par de veces para que el polvo comience a esparcirse. EXCELENTE AHORA! Con el paso de los días (creo porque se va distribuyendo mejor) su funcionamiento se vuelve mejor. Sigan las instrucciones y contraindicaciones ya que parece un artículo fácil pero requiere de su atención. Volveré a comprar sin dudarlo. Lo combiné con un lubricante de litio que también compré en Amazon y la verdad hasta gusto me da abrir mis puertas!
