J-B Weld 31310 All-Purpose RTV Silicone Sealant and Adhesive - 3 oz. - Clear

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

Works as expected, met or exceeded expectations.

Overall the product is great.The Good: It IS SAFE for aquarium usage for those wondering, and set timing is fairly accurateThe Bad: This product SMELLS, it has a very very strong chemical smell ( Yes I know it is silicone and doesn't smell like roses)The Sticky: The Silicone is very sticky too be expected but the real sticky part is the fact that the tube that the silicone comes in is a metal material and as soon as you roll it or squeeze too hard the tube splits and silicone will go all over your hands, so I would wear gloves.So I will recommend this product as far as aquarium usage goes, the material of the tube is really what took the star away simply for the fact that I lost a decent amount of the product on my hands and gloves.

It works as advertised

This is the best outdoor sealer I’ve ever used. I ran some CAT5 POE cables outside the house in the UK. I sealed the camera receptacle to the cable with this stuff. Eighteen years now in the UK elements and it’s still good. The sealant became a little cloudy after a decade, but no electrical/data connection was experienced. This is a replacement tube for the same brand I used then.If the sealer gets hard in the tube, but the tube is still pliable, poke a hole in the side. Squeeze out what you need, cover new hole with tape when done. Repeat until all useful product has been used.I always keep a spare tube when I open a fresh one.

I've used this at home and in every single factory job I've ever had in the last 40 years where I was on the maintenance team. Honestly I have never had this fail if you prepare the surface properly and wait for this to cure. Recommend this all the time to anybody who asks. Five stars easily!

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.
