J-B Weld 31316 RTV Silicone Gasket Maker and Sealant - 3 oz. - Blue

I'm familiar with this brand from past experience in hobbies and even when I was in the Navy. Worked well when my wife did a self-repair on her rain boot sole that developed a small crack where the sole flexed. She did the repair as I watched. Everything went as planned. Easy to use. The boot sat for 24+ hours to cure the seal. A wet test in the sink showed no leaks. A puddle test after the next rain also showed a great fix.

Works really well as a chaulk around my black granite and sink. Had to purchase this because at the time no one made a black chaulking for kitchen use. It is easy to apply and provides a good moisture barrier.

Great RTV silicone. Works Great Easy to Apply

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.

Good stuff. Works as advertised. Pay attention to ambient temperature at the time of application. Make sure your surfaces are clean.

Hard to get out of the tube most of it dry up. I Let set for 3 days because it was cold out when delivered. I got small job done will not buy again. Better go to the store to buy fresh tub.
