Works well, it's good quality silicone so should last not a gigantic container so keep it in mind if you have a large area to apply. Also if you try to squeeze the tube to strongly you'll pop the tube seams. Super water resistant and good consistency.

Works great! Used it for the black rubber strip at the bottom of my windshield. Easy to use. Can be a little messy so make sure to have a few paper towels handy..but worked just fine!

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.

JB Weld has been used in all facets of need. Holds up to any stress including steel. No smell, very functional and out preforms all other when directions are followed.

Used to seal around a light fixture on my brick facade. It looks so much better than if I had used white or clear. Other than the color it behaved just like any silicone sealant. The tube took serious squeezing, and I was careful not to apply too much pressure and break the bottom seam.
