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

Review: Good stuff. - This is the first time trying this product t and I am very happy with it. Holds well, sets quickly and did the job.
Review: Reliable sealant - 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

### ⭐⭐⭐⭐⭐ Highly recommend
*by I***O on February 21, 2026*

I bought this product because I needed a waterproof sealant that would bond well to a rubber surface. I wear waders for surf fishing and recently discovered I had a leak where the pants meet the boot and didn't want to have to order a new pair because of a small leak. I came to Amazon and looked at a few other products that basically advertise the same things but this one had the best reviews so I ordered it. I used a small amount with a paint brush on my waders and it covered the leak and bonded to the rubber material well. I am very impressed with its performance! I dries clear and dries pretty quickly. It does have a funny chemical odor, but that's to be expected when deal with silicone or epoxy.
