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. ## Frequently Bought Together - J-B Weld 31310 All-Purpose RTV Silicone Sealant and Adhesive - 3 oz. - Clear - Permatex 80050 Clear RTV Silicone Adhesive Sealant, 3 oz - Permatex 81158 Black Silicone Adhesive Sealant, 3 oz.
