Does the job with searching in stores for it. I used it to repair vehicle weatherstripping. It worked good for my application.

I cleaned the area, let it dry, then squeezed a narrow bead of silicone along the edge. The tube was easy enough to handle, though I went slowly so I would not make a mess. I pressed the trim into place and left the car alone while the sealant cured, following the directions on the package. A few days later, I checked it before driving to the library. The trim stayed put, and the black color blended in instead of drawing my eye to the repair. That was the part that made me glad I had bought this one. I still keep a damp cloth and a small scrap of cardboard nearby for jobs like this, since silicone can get on your fingers in a hurry.

I used this on this for a valve cover gasket and it worked alright. The tube basically blew out the back end when squeezing so be careful. But other than that it was fast easy and dried quick, which is what I needed. It’s as easy to remove as most siliocine caulkin. And it stuck pretty good. You get a decent amount per tube. More than you could ever need for 1-3 jobs. And the color was what I needed, but if you’re using this like you should, the color should matter as it’ll be hidden for the most part. Over all, it’s good but I which the actual tube it’s held in was More durable, no reason it should bust open just from squeezing it. But the size is good, you get a lot of it.

I cleaned and dried the area first, then squeezed out a thin bead and pressed the trim back in place. It got a bit messier than I expected, so I kept a paper towel nearby and worked slowly. The black color blended into the trim, making the fix less noticeable than a clear product would have. I left it alone overnight before using the appliance again, and the trim stayed put through my usual morning coffee routine.

Good deal

It is black. It vulcanizes at room temperature. The stock seems good, not too old.

The sealant & adhesive works great. However, as usual, after the first or second use, you'll find the cap is cracked and the top half-inch of the tube is dried out. The only way to salvage what's left is to poke a hole on the bottom of the tube and enjoy your last use. This J-B Weld Black Silicone isn't the only tube this happens with. It's more than a coincidence when this happens with almost all gooey stuff that comes in tubes. I believe the caps are designed to break so the contents will dry up and we'll have to buy more stuff. The best thing to do is after you use this stuff for the first time, is to cap it right. Perhaps put a small piece of a plastic bag over the opening before screwing the cap back on. Maybe steal the cap from your toothpaste tube and see if it fits. Good luck.

Muuuuuuuy bien producto, después de que el taller donde lo mando la aseguradora lo hiciera mal, esto me ayudó a sellar las grietas donde se le metía el agua al coche Excelente producto

100% recommend. I bought this off the back of a chat with AI on the best silicone sealer for a new Scorpion GPF back exhaust. Couldn’t be happier with the seal. I made 2 rings, approximately 2-3mm thick inside the female end of each of the 2 connecting pipes for my i20n. Formed a complete seal and have half of it left, which probably won’t be used. No air leaks, no smell or burning. I did give it around an hour to set/ cure after putting bits of the car together having rented a ramp for 6hrs (fit other bits too). On initial startup underneath the car there was zero burn off or smells etc. Highly recommend the copper silicone version.

It's nice no smell too much and bonds very fast

I was happy with this glue. It was easy to use and control. It was a great alternative to hot glue . The items I repaired stayed together well, and drying time was reasonable. I’d buy this again and I recommend it for household fixes. Everything I used it on was successfully repaired.

Muy buen producto, lo ocupe para sellar bien mis calaveras de mi carro y quedaron perfectas
