Good stuff I used it to seal some new after market headlights which were getting water in the lense problem solved

Overall, this product works well and is safe for aquarium use, which is great peace of mind for fishkeepers.The Pros: It's definitely aquarium-safe, and the set time is accurate as advertised.The Cons: Be aware—it has a strong chemical smell. While it's expected for silicone, it's quite intense.The Caution: The silicone is sticky, which is normal, but the real issue is the packaging. The tube is made of metal, and if you squeeze or roll it a bit too hard, it can split open, leading to silicone spilling onto your hands. I’d recommend wearing gloves to avoid a mess.In terms of functionality, I would recommend this product for aquarium applications. However, the packaging could be improved, as I ended up losing a fair amount of silicone due to leakage.

Used J-B Weld 31310 clear RTV silicone to seal a shower door and fix a cracked plastic light cover. It adhered well to both glass and plastic, cured evenly, and held up to water without peeling. No strong odor, and easy to smooth out. Only complaint: the tube split near the bottom halfway through, which wasted some product. The sealant works great

Worked perfectly

Professional plumber, mounted / installed x3 under mount lav sinks. This stuff is great!!

Works great

I bought this to attach items in snowglobes, and to seal the bottoms. It's a small tube, designed for small jobs. I used half a tube for 2 snowglobes. It came with a pointed cap to squeeze out a fine bead, but it seemed hard to squeeze out of the cap--I'm so used to using a calking gun. It was much easier to squeeze it right out of the tube. This sealant is thick coming out, but you can manipulate it for a while before it sets up. So it'a a totally different consistency than silicone caulk. It seemed to me that it dried in a couple of hours, and totally cured in 24 hours. It is crystal clear. There is a smell for about an hour, but not too bad. I needed a waterproof seal, and this is it. I think normal people use this on aquariums.UPDATE: My grandson chose the Santa snow globe, but just after the ride home in the car (not bumpy), the ceramic Santa came loose. The JB Weld Silicone Sealant kept the bottom of the snowglobe on, but didn't hold the ceramic Santa to the base of the snowglobe. Be advised that this sealant doesn't work on polypropylene plastic. Instead, I recommend E-6000 glue, which is like a gel superglue.
