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

I recently used this silicone sealant for some minor household repairs, and it turned out to be a fantastic choice! 🛠️ The J-B Weld All-Purpose RTV Silicone Sealant & Adhesive is perfect for fixing leaks, sealing gaps, and even some automotive jobs. 🚗 🔧 The application process is straightforward, and the product works really well on a variety of surfaces, including glass, metal, and plastic. The sealant dries clear and provides a strong, waterproof bond that’s resistant to the elements. 🌧️ I especially appreciate that it doesn't shrink or crack, ensuring long-lasting durability. 💪 🧰 Whether you're fixing a leaky pipe, sealing around a window, or working on your car, this sealant provides reliable performance. It's also safe for use around sensors and is resistant to mold and mildew, which adds to its versatility. 👌 I highly recommend this product to anyone in need of a versatile, durable sealant. It’s especially useful for DIY projects, household repairs, or automotive fixes. 🏡

We recently purchased a new car. It is parked in the garage every night. The other day I noticed that a plastic trim panel on the passenger door had some scratches on it. Time to investigate! Mounted on the wall next to the door there’s a 2 inch pipe with a clamp fitting that has a protruding piece with a rough edge. This was scratching the trim when the door was opened. I took the JBweld silicone sealant and built a bumper over the rough metal. Took 3 coats to get what I wanted, but it works perfectly. This stuff is easy to use, durable and well worth the price.

Overall the product is great. The Good: It IS SAFE for aquarium usage for those wondering, and set timing is fairly accurate The 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.

Works as expected.

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 went to go use it and it exploded out of the back end..I didn’t even apply that much pressure either. I was disappointed but then they gave me a replacement for it so changed the review to five stars. Thanks!
