## Description

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

Review: Good sealant, use your own applicator. - Used this to seal up an aquarium and it worked super well. It hardened fully in about 48 hours, but I probably could've scraped off the excess after 24. It's super clear and blends into the background. The applicator didn't work very well, so I put it in a Ziploc and piped it on like frosting, which worked much better. Aquarium is watertight now.
Review: Excellent - Does what it says

### ⭐⭐⭐⭐⭐ Gorgeous!
*by G***Y on May 16, 2026*

Great stuff for repairing things that need to be water- and weatherproof. Beware the bottom of the tube blowing out on you. Before I used it, I duct-taped the bottom of the tube to prevent a blowout and the mess that comes with it. So far so good.
